It makes no sense conceptually, and I am confident that the variance component estimates you get from -xtreg- with that are meaningless and uninterpretable.įinally, the title of your post is inaccurate: you didn't use -reg-, you used -xtreg-, which is a different command.įinally, the title of your post is inaccurate: you didn't use -reg-, you used -xtreg-, which is a different command. You are, in effect, specifying both fixed and random effects in the same model. So I recommend you abandon your use of -xi:-, and even try to forget you ever knew about it.Īnother aside: after you have -xtset industry year-, it does not make sense to include industry indicators among the variables in your random effects model. The -margins- command is, in my experience, one of the top ten most useful commands in all of Stata.
If you use -xi:-, you will be unable to make use of the -margins- command following the estimation. Certainly there is no reason to every use -xi:- with -xtreg. There are still a few situations where factor variable notation does not work, but they are either esoteric or associated with archaic commands whose function has been replaced by more modern commands that do support factor-variable notation. The automatic generation of indicator variables is taken care of by factor variable notation now. You should seldom, if ever, use the xi: prefix any more. Certainly if you have, say just a dozen or so industries, most would agree that the cluster-robust vce should not be used here.įinally, a couple of asides. Experts disagree about just how small is small for these purposes, but it might be a consideration here. If the number of cluster is small, vce(cluster) is not an improvement over the non-robust vce, and in fact it can be substantially worse. One question that is important here is how many industries you have in your data. But it is not invariably the case, as you have discovered. You cannot get an unclustered -xtreg, vce(robust)- in Stata: it is not implemented, because it is not a valid vce estimator.Īs for the expectation that the standard errors will be lower with the non-robust vce estimator, that is often, perhaps usually the case.
(Note to StataCorp: this is not clear in the help file.) So the fact that you got the same results with the second and third is not at all surprising.

Browse this website to learn more about VCE software.The manual documentation for -xtreg- clarifies that for this command, -vce(robust)- is implemented as -vce (cluster panelvar).
