web-static.stern.nyu.edu“robust standard errors,” has also reduced the concern over heteroskedasticity. If the sample size is large, then robust standard errors give quite a good estimate of standard errors even with heteroskedasticity. If the sample is small, the need for a heteroskedasticity correction that …

Useful Stata Commands 2019 - Rensselaer Polytechnic Institute
homepages.rpi.eduMost commands work the same in Stata versions 12, 11, 10, and 9. Throughout, estimation commands specify robust standard errors (Eicker-Huber-White heteroskedastic-consistent standard errors). This does not imply that robust rather than conventional estimates of Var[b|X] should always be used, nor that they are sufficient.
