mixrandregret: A command for fitting mixed random regret minimization models using Stata

The command can fit a mixed version of the classic RRM model introduced in Chorus (European Journal of Transport and Infrastructure Research. 2010. 10: 181–196). It allows the user to specify a combination of fixed and random coefficients. In addition, the users can specify normal and log-normal distributions for the random coefficients using the commands’ options. Finally, the models are fit using simulated maximum-likelihood procedures using numerical integration to simulate the models’ choice probabilities.
