Regression with Stata Chapter 4 – Beyond OLS

WebIf variance() is not speciﬁed, Stata assumes that D has been posted using ereturn post; robust will then automatically post the robust covariance matrix V and replace D. minus(#) speciﬁes k= # for the multiplier n=(n k) of the robust variance estimator. Stata’s maximum likelihood commands use k= 1, and so does the svy preﬁx. regress ... WebSep 28, 2024 · In Stata, simply appending vce (robust) to the end of regression syntax returns robust standard errors. “vce” is short for “variance-covariance matrix of the estimators”. “robust” indicates which type of variance-covariance matrix to calculate.
