WebApr 23, 2024 · Answer (A bit too late but for the use of other users) In short, if you only want to use the missing argument in the smf.ols function, there is no way to make it work and, I think, there should not be one, given the current state of the package. The reason is exactly as you mentioned: “the rows with missing observations aren’t getting removed” and they …

WebArguments. fml. A formula representing the relation to be estimated. For example: fml = z~x+y. To include fixed-effects, insert them in this formula using a pipe: e.g. fml = z~x+y fe_1+fe_2. You can combine two fixed-effects with ^: e.g. fml = z~x+y fe_1^fe_2, see details. You can also use variables with varying slopes using square brackets ...

WebWith Assumption 4 in place, we are now able to prove the asymptotic normality of the OLS estimator. Proposition If Assumptions 1, 2, 3 and 4 are satisfied, then the OLS estimator is asymptotically multivariate normal … WebUnder this sampling scheme, the observations form different time periods are pooled together and OLS is conducted on the pooled sample. This differentiates it from a panel (or longitudinal) sample where the same observational units are repeatedly observed. In this case, the researcher typically uses a within (fixed effects) or similar estimator ...
Webtimator precision. Instead, if the number of clusters is large, statistical inference after OLS should be based on cluster-robust standard errors. We outline the basic method as well as many complications that can arise in practice. These include cluster-speci c xed e ects, few clusters, multi-way clustering, and estimators other than OLS.
