WebMay 29, 2024 · Note, -robust- handles uncertainty differently depending upon whether you're estimating your model using -reg- or -xtreg, fe-. For instance, -reg- is robust to heteroscedasticity—but results in unclustered standard errors. Once you run -xtreg, fe-, Stata will automatically cluster on your panel variable. And what does it suggest about … WebJan 8, 2024 · Sorry for the delay.. I think I have to clarify this question a little bit more. So what I am looking for, is a function in which I can provide both the vcov matrix ( the vcov2sls), and have robust and clustered standard errors.However it seems that they both pertain to the vcov matrix. So if I supply one, I already have to make sure the se's are …
Webeach dimension (e.g. firms and years).
