WebHow can I compare regression coefficients across 3 (or more) groups? Stata FAQ Sometimes your research may predict that the size of a regression coefficient may vary across groups. For example, you might believe that the regression coefficient of height predicting weight would differ across 3 age groups (young, middle age, senior citizen). WebTo establish which group has the lowest variance you can examine the residuals from a model without heteroskedastic errors. In this example, examination of the residuals shows that the residual variance is smaller for females than males. The code below creates two new variables, male, and nid.

For instance, a study of innovation might want to estimate patent citations as a function of patent characteristics, standard fixed effects (e.g. year), and fixed effects for each inventor that worked in a patent.
