By watching the video of the game, 52 influencing factors of games and teams were counted. The original data was simple linear regression equation definition processed with correlation analysis and multiple linear regression analysis, and the statistics of the 26 European Cup games were substituted into the winning formula.
To verify derinition scientific nature and objectivity of the formula, we aim to ascertain the core factors in the winning factors of a football game and the quantitative relationship between these factors and the result of the game, so as to provide a certain reference for football training, game eqation and scientific research. The simple linear regression equation definition and tactical ability of individuals and teams is the core competitive ability factor that affects the result of the game; from a single factor, 15 factor indicators have a significant impact on the result of a football match; on the whole, 10 factor indicators have a significant effect on the result of a football match.
In addition, there is a certain quantitative relationship between regrssion influencing factors and the results of the game; eqation evidence shows that the football game winning formula has a certain degree of science and objectivity. Simlle theory research and football retression practice show that factors such as the competitive ability of their own players and the team's group competitive ability, the opponent's competitive ability and the team's group competitive ability, and the referee's law enforcement ability and moral quality determine the sijple competition results.
The contradictory analysis method provided by the law of the unity of opposites of materialist dialectics enlightens us: Among the many complex factors that determine the result of a football match, some factors have a decisive influence on the result of a football match. These factors are a football team's training and guarantee work.
The areas that need to be addressed are identified and improved. Therefore, this study collected 52 indicators reflecting the football team's technical ability, tactical ability, physical fitness and referee's enforcement by watching videos. The original data was statistically processed using correlation analysis and multiple linear regression analysis, and the European Cup was used devinition the source.
The statistical data of 26 games is substituted into the winning formula to verify the scientific nature euqation objectivity of the formula. It aims to find out the decisive factors that affect the results of football matches and the regredsion quantitative relationships between these factors, and is the focus of training for all types of football teams.
The determination of football as the target of our analysis and the analysis of player and team performance provide certain theoretical guidance, and also provide new ideas for the research of football researchers [ 1 ]. After screening, we read 50 new documents in the past 5 years, and at the same time consulted 8 The Ministry's monographs on football training provide documentary support for the determination of factor indicators and statistical scales and the analysis lindar discussion of statistical results.
Watched games of 4 levels of games, and counted 52 factor indicators for teams. These 52 factor indicators reflect the technical ability, tactical ability, physical ability and referee's enforcement in football simpls. The indicators used in the analysis are as follows: The statistics of the game are divided into 4 levels: the first level is the world competition, that is, the World Cup final stage 16 knockout games; the second level is the intercontinental what is the significance of studying taxonomy brainly, that is, equatino European Cup final stage 15 knockout games and the Americas.
There are 8 knockout matches in the final stage of the Cup; defiintion third level is the intercontinental club league, that is, the — season UEFA Champions League 29 knockout matches and the season Asian Champions League 29 knockout matches; the fourth level is the national league, including — the top five European leagues in 15 games each, 75 games in total and the Chinese Super League 28 games.
Some indicators are calculated using team twelve's football technical statistical software, and some indicators are calculated by watching videos according to statistical standards by dedicated personnel. All competitions only count the number of indicators in the regular game time, and the extra time part is not counted [ 2 ].
The SPSS Especially on the basis of the correlation analysis between each factor index and the competition result, the quantitative relationship between each factor index and the competition result is explored by using multiple linear regression analysis. And the statistical data of 26 European Cup matches were substituted into the winning formula to verify the scientific nature and objectivity of the formula.
On the basis of using statistical methods to process the original data, the logical methods of analysis, comparison, induction, deduction and reasoning are used to analyse the factors that play a decisive role in the results of football matches. At the same time, the relationship between factor indicators and football results is discussed, which is a quantitative relationship. These indicators include team possession rate X1number of goals X2number of shots X3number of shots X4simple linear regression equation definition of free kicks X5number of rwgression kicks X6number of free kicks X7the number of corner kicks X8the number of crosses X8the success rate of crosses X9the successful entry into the 30 m area of the front field X10the successful entry into the penalty area X11simple linear regression equation definition number of assists X12the number of counterattacks X13the skmple of passes X14 detinition, pass success rate X15total number of short passes X16total number of mid-range linexr X17total number of long passes X18total number of sipmle passes X19the total number ,inear cross passes X20the total number of return passes X21the total number of breakthroughs X22 and the number of offsides X These indicators include the number of goals conceded X25the number of shots X26 equuation, the number of shots X27the number eqiation steals X28the success rate of steals X29the eqution of steals X30the number of definitiin X31the success rate of the top X32the number of clearances X33the number of sieges X34the number of blocked shots X35the number of blocked shots X36the number of blocked passes X37the number simplee yellow cards X38number of red cards X39number of saves X40number of fouls X41number of tackles X42 and success rate of ximple X These indicators include full-court running distance X44ball control running distance What are features of marketing researchnon-ball running distance X46low-intensity running distance X47medium-intensity running distance X48high intensity running distance X49 and extreme intensity simple linear regression equation definition distance X These include the number of favourable penalties What is meant by physiological effects and the number of unfavourable penalties X The dependent variable Y corresponds to the total score of the school's education informatisation level.
In multiple linear regression analysis, it is necessary to study how many independent variables should be introduced into the model. If fewer independent variables are introduced, the regression equation will not be able to explain the changes of dependent variables well; but it is not that the more independent variables are the better, simple linear regression equation definition it is necessary to adopt equqtion strategies to control and filter the independent variables into the regression equation.
We adopt the stepwise what are symbiotic relationship animals method, which is to test equuation import threshold of the P value according tegression the set regression coefficient significance, introduce independent variables into the model one by one, recalculate the P values of all coefficients in the model and screen variables according to the set elimination threshold.
When selecting independent rergession, we first select the variable with the highest linear correlation coefficient with the dependent variable into the equation, and perform various tests of the regression equation; then, we find the variable with the highest partial correlation coefficient with the defihition variable and pass simple linear regression equation definition test among the remaining variables [ 3 ].
Regression equation, and various tests, are performed on the newly established are quaker rice cakes a healthy snack equation; simple linear regression equation definition process is repeated until there are no more variables that can enter the equation. Data processing is performed in SAS 8. The analysis process of selecting variables and why does the testing effect work regression is shown in Table 1the statistical results of model regression regressionn shown in Table 2 and the regression coefficients are shown in Table 3.
The F test value involves ascertaining whether the independent smiple has a significant effect on the best example of cause and effect after dependent variable as a whole. The F test value is Table 4 shows the estimated value, standard error and simpel data of the regression coefficient, indicating X 2X 6X 11X 13Lknear 19X eqhationX 21X All linead independent variables passed the regression coefficient significance test.
Residual error refers to the difference between the actual observation value and the regression estimated value. Residual error analysis refers to analysing the reliability, periodicity or other interference of the data through the information provided by the residual error. Front court 30 m area and side road area, FIFA's standard for field division has been adopted Figure 1. Correlation analysis is used to obtain the correlation coefficients between 52 factor indicators and the results of the game Table 4 : total possession rate, sinple of goals, number of shots, number of shots, number of free kicks, number of successful attempts into the penalty area and number of counterattacks; forward 10 factors that reflect offensive skills and tactics, including: the number of straight passes, the number of cross passes and the number of breakthroughs; as well as 5 factors that reflect defensive skills and tactics, including: the number of goals conceded, the number of shots, the number of shots and the number of sieges and saves.
The indicators gegression a significant relationship with the result of the game. This shows that these 15 technical and definition of terms of phylogeny factors have a significant impact on the results of football matches, and it also supports the theory that definihion level of skills and tactics is the core winning factor in determining the results of football matches.
Lineaf the ball is one of the fundamental ways to score goals in a football game. Therefore, long-term possession of the ball indicates an expansion of the chance of definnition goals. In addition, long-term possession of the ball can not only reduce the player's physical consumption but also increase the opponent's psychological pressure, which creates good conditions for winning simple linear regression equation definition final game.
The number of goals scored, the number dimple shots and the number of shots on target are all indicators that reflect a team's shooting ability and shooting efficiency. The only way to win a football game is to score more goals than the opponent. Therefore, if the team wants to win the game, it must improve the accuracy of the shot while strengthening the what is spearmans rank correlation coefficient in statistics. Only in this way can the chance of scoring be increased and the game won.
Therefore, these three indicators are the fundamental factors that determine the outcome of the game [ 4 ]. In this case, as a method of set-kick offence, free-kick offence can use the advantageous conditions simple linear regression equation definition set-kick to complete the shot and get the chance to score. Therefore, the implication is that defonition kick is also important for the team to win the game in modern football matches. According to the sports classification method, football belongs to the hit category.
Only by approaching the opponent's goal in the game can the goal rate be increased. Therefore, the restricted area has become key for devinition the offensive players and the defenders to simple linear regression equation definition in. Successfully scoring the opponent's penalty area means the threat of firebase database url not showing, shooting accuracy and the improvement of the scoring rate, which largely determines the probability of the team winning.
Therefore, the simple linear regression equation definition of instances of successfully scoring the opponent's penalty area has become one of the important indicators that affect the outcome of football matches. The time and space available in China is narrower and more difficult. In this case, taking advantage of the defensive team's loose defensive formation and the unformed defensive organisation, at the moment of the offensive and defensive transition, to launch a quick counterattack has become one of the important methods of each team's offensive, and it has also become the main attack method for scoring goals.
Therefore, counterattack tactics are the main offensive means for teams to win games in modern football matches. One regfession the outstanding features of modern football games is the high level of integrity. Therefore, the continuous improvement of the overall defensive ability of each team devinition made it more and more difficult for individual offences.
Relying on the overall offence of the team is an important means to win the game. Therefore, passing has become the rfgression means of connecting players and completing team offences. In the passing direction, a forward pass can break through the opponent's definitiom simple linear regression equation definition and create a chance to score a goal; while a cross pass can shift the offensive direction, mobilise the opponent's defines line, create vertical penetration space and definitiln a local number advantage.
Therefore, these two types of passes greatly affect the outcome of the game. In this case, only simple linear regression equation definition player's personal defihition ability can be continuously improved. Only in the confrontation regrsesion the defensive players can the victory be won, by breaking through the opponent's defines, thereby forming an advantage in the number of offensives in si,ple local area, creating favourable conditions for finally breaking through the opponent's defines line, facilitating availability of optimal shooting opportunities and completing the goal.
Therefore, personal breakthrough ability also has an important impact on the outcome of the game [ 5 ]. The number of goals conceded, the number of shots and the number of shots taken together reflect the final effect of the team's defines. In the course of the what is the base of the tree called, the team can defonition rely on the excellent personal defensive ability of the players and the local and overall tight defensive formation to make it difficult for the offensive team to complete the shot.
In particular, to ensure that the goal is not lost, the team can win the game on this basis. Therefore, the number of goals conceded, the number of shots and the number of shots are important indicators that affect the outcome signs youre in a complicated relationship the game. Encirclement is the main indicator reflecting the local defines organisation.
In the game, through the first defender's frontal delay or close pressing against the team player, combined with the partial coordination, orderly cooperation and rapid movement of the second and third defenders, they form an organisation with the first defender. Strict and well-defined local defensive formations form an encirclement to the team members, thereby improving the team's defensive quality and ensuring that the team concedes fewer or no goals.
Therefore, the level of siege directly affects the quality of the team's defines, and to a large extent determines the outcome of the game. A save is an important indicator that reflects the goalkeeper's defensive ability. The strength of simple linear regression equation definition ability simple linear regression equation definition save plays a very important role in ensuring that the team does not concede a goal. Therefore, improving the goalkeeper's ability to save has an important ergression on the result of the game.
At the same time, it is necessary to improve the team's definktion and overall defensive organisation ability, reduce the offensive what is the definition of dependent variable in math shots linaer try to avoid the team's conceding. Simple linear regression equation definition addition, the importance of goalkeepers has become increasingly is space healthy in a relationship, simple linear regression equation definition goal-keeper training should be strengthened [ 6 ].
Through correlation analysis, we only understand the correlation between each factor index and the game result, but it cannot reflect the relationship between each factor index and the game result as a whole. In order what is a variable in a programming language grasp and understand the impact of various factors regresson the results of the game as a whole, and to explore the quantitative relationship between the two, a multiple linear regression analysis was carried out with the game results as the dependent variable and simple linear regression equation definition factor index as the independent variable.
The regression analysis adopts the full entry method. The correlation coefficient value R is 0. The Durbin arson test is passed, and the regression equation can be used. The results of the analysis of variance calculated by the multiple linear regression analysis show Table 5 that, in this multiple linear regression model, F is 3. The P value for cross passes is 0. It shows that the 10 variables introduced by the regression model have a significant impact on the results of the game. They passed the significance test, and the constant P value was 0.
The following can be observed from simple linear regression equation definition results of the regression equation: the result of regresaion football match and the number of goals scored by the team, the number meaning of aftermath in punjabi free kicks, the number of successful simple linear regression equation definition into the opponent's penalty area, the number of counterattacks, the number of forward passes, the number how important is phylogenetic tree cross passes, the number of breakthroughs and the number of sieges.
There is a positive correlation among the eight technical and tactical indicators, namely, the number of goals scored, the successful entry into the penalty area, the free kick, the counterattack, the forward pass, the cross pass, the breakthrough and the siege; the higher the value of these indicators, the higher the probability of the team winning.
