11.44 Building a multiple linear regression model. Let’s now build a model to predict the lifesatisfaction score, LSI.

a. Consider a simple linear regression using GINI as the explanatory variable. Run the regression and summarize the results. Be sure to check assumptions.

b. Now consider a model using GINI and Life. Run the multiple regression and summarize the results.

Again be sure to check assumptions.

c. Now consider a model using GINI, Life, and Democracy. Run the multiple regression and summarize the results. Again be sure to check assumptions.

d. Now consider a model using all four explanatory variables. Again summarize the results and check assumptions.
