WebJun 29, 2024 · A robust regression effectively performs a weighted regression such that extreme observations carry less weight upon the overall effect, compared to non-extreme observations. Both Stata and R can perform robust regression using the same kinds of weights: > Two types of weights are used. Webrreg performs one version of robust regression of depvar on indepvars.
