In Stata 16, we introduce a new, unified suite of commands for modeling choice data. We have added new commands for summarizing choice data. We renamed and improved existing commands for fitting choice models. We even added a new command for fitting mixed logit models for panel data. And we document them together in the new Choice Models Reference Manual. And here’s the best part: margins now works after fitting choice models. This means you can now easily interpret the results of your choice models. While the coefficients estimated in choice models are often almost uninterpretable, margins allows you to ask and answer very specific questions based on your results. Say that you are modeling choice of transportation. You can answer questions such as • What proportion of travelers are expected to choose air travel? • How does the probability of traveling by car change for each additional $10,000 in income? • If wait times at the airport increase by 30 minutes, how does this affect the choice of each mode of transportation? What else is new? You now cmset your data before fitting a choice model. For instance, . cmset personid transportmethod Then, you use cmsummarize, cmchoiceset, cmtab, and cmsample to explore, summarize, and look for potential problems in your data. And you use cm estimation commands to fit one of the following choice models: • cmclogit conditional logit (McFadden’s choice) model • cmmixlogit mixed logit model • cmxtmixlogit panel-data mixed logit model • cmmprobit multinomial probit model • cmroprobit rank-ordered probit model • cmrologit rank-ordered logit model Unlike the others, cmxtmixlogit is not renamed and improved. It is completely new in Stata 16, and
Bayesian autoregressive models and more. Extensive Bayesian inference is available after estimation, including Markov chain Monte Carlo (MCMC) diagnostics, posterior summaries of linear and nonlinear functions of parameters, interval hypothesis testing, and model comparison using Bayes factors; see [BAYES] Bayesian postestimation for a full list of features.
