How to use robust standard errors in stata
Weberrors. HC standard errors are examples of “sandwich” standard errors. Conceptually, both the usual OLS standard errors and the HC2 standard errors come from the same description of the covariate space (the “hat” or “projection” matrix), but the HC2 standard errors give less weight in their calculation to high-leverage points.
