Lecture: IV and 2SLS Estimators (Wooldridge’s book chapter 15)
www.fsb.miamioh.eduIt is straightforward to account for heteroskedasticity. The robust variance-covariance matrix for bˆ 2SLS allowing for heteroskedasticity is robust var-cov(bˆ 2SLS)= X 0PX 1 X PWPX X PX 1 where W = E(UU0): To estimate the meat in the middle of that sandwich, using X0PWbPX = Xb0WbXb= n å i=1 uˆ2 i bx ibx 0 i where ˆu denotes the 2SLS ...

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.
