Hi, I am beginning an exercise that must achieve the following:

For each of your OECD predictors, develop five single-year simple regression models on OECD data, selecting either the OECD variable "Life Satisfaction" or WHR variable "Life Ladder" as the dependent variable. That is, you could develop simple regressions for each of the predictors of "Life Ladder" for each year of data that you consider. We are using data from five separate years in order to obtain five models for each predictor for meta analysis.

How do I do that, and compute the Correlation and determination coefficients obtained for the different regression models?
