Statistical Software Components, Boston ...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.Can I use the same command you provided in #8 for the following situation: I want to select a sample in a balanced panel data in a way I keep the representativeness of the variable "region" and also keep the panel balanced with information of the person id for each year of the panel. Thanks in advance!Setting up panel data in Stata involves a few key steps, including: Importing the data into Stata – This can be done by using the “ import ” command or by opening the data file directly in Stata. Reshaping the data – This step involves organizing the data into the appropriate format for analysis.Therefore, Stata has an entire manual and suite of XT commands devoted to panel data, e.g. xtreg, xtlogit, xtpoisson, etc. Panel Data offer some important advantages over cross-sectional …Staring at our data all data points at the same time, "has the advantage" that does not impose any structure on our data, it just takes our data as it is. Generally speaking, Driscoll-Kraay standard errors do not have an advantage over Newey-West standard errors for panel data. The former assume less than the latter, and might deliver less.The webpage provides the PDF version of the Stata manual for panel-data analysis.
