Multiple linear regression is used to establish the linear relationship between a dependent and more than one explanatory variables; it is a generalization of the simple model. Students must be able to understand how the Ordinary Least Squares (OLS) method works, to compute and interpret the R^2, the adjusted R^2, the standard error of the regression, the F-test, the t-tests and confidence intervals for the parameters.
