Since Stata provides inaccurate R-Square estimation of fixed effects models, I explained two simple ways to get the correct R-Square. The main emphasis will be on methods for panels where the cross-section dimension is large and the time-series dimension is small. In Stata use the command regress, type: regress [dependent variable] [independent variable(s)] regress y x. 1/vif is the tolerance, which indicates the degree of collinearity. Panel data, by its very nature, can therefore be highly informative regarding heterogeneous subjects and thus it is increasingly used in econometrics, financial analysis, medicine and the social sciences.
