WebApr 2, 2024 · Stata uses a small sample adjustment for their GLM function, in which the standard sandwich variance (obtained via the vce (robust) command) is scaled according to the sample size and the number of parameters in the model. R uses no such adjustment. Webvce(vcetype) speciﬁes the type of standard error reported, which includes types that are derived from asymptotic theory (ols), that are robust to some kinds of misspeciﬁcation (robust), that allow for intragroup correlation (cluster clustvar), and that use bootstrap or jackknife methods (bootstrap, jackknife); see[R]vce option. vce(ols), the …
