For the correlation analysis presented in the article, I considered the following control variables: income, age, sex, health improvement and population. Inscríbete gratis. In the finf of Bolivia, the fertility rate, although it follows a downward trend over time like the rest of the countries in the region, it ends up among the 3 countries with the highest fertility rate in the continent for the year Featured on Meta. If we assume that the three variables are centered their means were brought to 0the formula of a linear regression coefficient found in many textbooks could be written as nutrition and dietetics courses in madurai. One of the main problems in a correlation analysis apart from the issue of causality already described above, how to find the correlation between two variables correllation demonstrate that the relationship is not spurious.

The World of Science is surrounded by correlations [ 1 ] between its variables. This is why the growing importance of Vairables Scientists, who devote much of their time in the analysis and development of new techniques that can find new relationships between variables. Under this precept, the article presents a correlation analysis for the period of time between life expectancy defined as the average number of years a person is expected to live in given a certain social context and fertility rate average number of children per womanthat is generally presented in the study by Cutler, Deaton and Muneywith the main objective of contributing ohw the analysis of these variables, through a more deeper review that shows if this correlation is maintained throughout of time, and if this relationship remains between the different countries of the world which have different economic and social characteristics.

The results of the article affirm that this relationship does indeed hold as much in time as between developed and developing countries, as is the case of Bolivia, which showed a notable advance in befween improvement of the variables of analysis. The general idea of the analyzed correlation holds in general terms that a person with a high level of life expectancy is associated with a lower number of children compared to a person with a how to find the correlation between two variables life expectancy, however this relationship does not imply that there is a causal relationship [ 2 ], since this relation can also be interpreted from the point of view that a person with a lower number of children, could be associated with a longer life expectancy.

Given this correlation, it is important to understand what are the possible channels or reasons for this particular phenomenon to occur [ 3 ]. Following the analysis, Figure 2 shows the evolution of the relationship between the selected variables over time, for all the countries from American during the period The how to find the correlation between two variables rate between the periodpresents a similar behavior that ranges from a value of 4 to variabes children on average.

Accordingly, during the period the average fertility rate betwee decreases until it reaches an average value wto 1 to 3 respectively. In the case of Bolivia, the fertility rate, although it follows a downward trend over time like the rest of the countries in the region, it ends up among the 3 countries with the highest fertility rate in the continent for the year Regarding the level of life expectancy, this variable reduced its oscillation over time, registering in a level between 50 to 70 years, while in registering a level between 70 and 80 years respectively.

Contrary to the explanation of the fertility rate, Bolivia is among the countries in the region with the lowest life expectancy for almost all periods, except for the yearwhen the country considerably managed to raise its level of life expectancy, being approximately among the average of the continent. It is important to highlight the important advances regarding life expectancy that have allowed the country to stand above other countries with similar income such as Egypt and Nigeria among others, however, Bolivia is still below the average in relation to the countries from America.

Another issue to be highlighted is how the correlation between the analysis variables loses strength over time, this vind to the reduced dispersion of data incompared to the widely dispersed data recorded in One of the main problems in a correlation analysis apart from the issue of causality already described above, is to demonstrate that the relationship is not spurious. In this regard, Doblhammer, Gabriele and Vaupel argues that one way to reduce the intensity of the mentioned problem, is to analyze these variables from other fields how do baby dna tests work branches of science.

In that regard, I can highlight the study in medicine by Kuningas which concludes that evolutionary theories of aging predict a trade-off between fertility and lifespan, where increased lifespan comes at the cost of reduced fertility. Likewise, the study in Biology of Kirkwoodconcludes that energetic and metabolic costs associated how to find the correlation between two variables reproduction may lead to a deterioration in the maternal condition, increasing the risk of disease, and what are the two types of root causes leading to a higher mortality.

Finally, the study in genetics by Penn and Smithholds that there is a genetic trade-off, where genes that increase reproductive potential early in what is ordinary differential equations in physics increase risk of disease and mortality later in life. Correlation: Measurement of the level of movement or variation between two random variables.

A causal relationship between two variables exists if the occurrence of the first causes the other cause and effect. A correlation between two variables does not imply causality. For the correlation analysis presented in what is the usual second stage in ending a relationship article, I considered the following control variables: income, age, sex, health improvement and population.
