Stata's didregress and xtdidregress commands fit DID and DDD models that control for unobserved group and time effects.didregress can be used with repeated cross-sectional data, where we sample different units of observations at different points in time.xtdidregress is for use with panel (longitudinal) data. These commands provide a …Nov 16, 2022 · Autocorrelation. Iterated GLS with autocorrelation does not produce the maximum likehood estimates, so we cannot use the likelihood-ratio test procedure, as with heteroskedasticity. However, Wooldridge (2002, 282–283) derives a simple test for autocorrelation in panel-data models. Drukker (2003) provides simulation results showing that the ... To the best of my knowledge and research in the statalist forums, I came to notice that there are several options to regress. Option 1: xtnbreg, fe such as: Code: xtset state year xtnbreg new_firms bank_concentration vc_firms GDP_growth i.year. Option 2: nbreg with dummy vectors. Code:With Stata 16's new cmxtmixlogit command, you can fit panel-data mixed logit models. Like other choice models, mixed logits model the probability of selecting alternatives based on a group of covariates. Mixed logit models are special in that they use random coefficients to model the correlation of choices across alternatives.
