Stata fits quantile (including median) regression models, also known as least-absolute value (LAV) models, minimum absolute deviation (MAD) models, and L1-norm models. Median regression estimates the median of the dependent variable, conditional on the values of the independent variable. This is similar to least-squares …

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.

This course focuses on the interpretation of panel-data estimates and the assumptions underlying the models that give rise to them. The course is geared for researchers and practitioners in all fields. Two elements are immediate. First, the panel structure is crucial here. For each panel, we must identify the first (or perhaps last) occurrence of a state, say, state == 1. To experienced Stata users, this should suggest that you use by varlist: , here by id:.

In a pooled dataset with heteroskedasticity you should use robust standard errors. This will adjust the standard errors to take account of the heteroskedasticity. If you have a panel dataset then you are probably better off using clustered standard errors as your heteroskedasticity will be related to the reporting of each unit (firms).Dear Stata community, currently, I am trying to decide whether my data is normally distributed or not using the Jarque-Bera test.
