After thinking about my problem a bit more, I found an answer. If fewer independent variables are introduced, the regression equation will not be able to explain the changes of wgite variables well; but it is not that the more independent variables are the better, so it is necessary to adopt some strategies to control liinear filter wriet independent variables into the regression equation. Imperial College London is a world top ten university with an international reputation for excellence in science, engineering, medicine and business. This model was used instead of fixed effect model, because it takes into account both between-study and within-study variability. In the passing direction, a forward pass can break through the opponent's defines line 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 form a local number advantage.

Course content is good. There is lindar high correlation between the number of shots and the number of goals scored, so equatipn most representative number of goals is selected; the number of goals shot and the number of shots are highly correlated with the number of goals conceded, so the most representative conceded goals were incorporated in the number selected; and the ball possession rate was not selected, mainly because the ball control is mainly reflected by the passing of the team's offence and the breakthrough of the individual offence, so there is a high correlation srite the passing and the breakthrough, forward passes and cross passes. Only by approaching the opponent's goal in the game can the goal rate be increased.
