logitr estimates multinomial (MNL) and mixed logit (MXL) models in R. Models can be estimated in "Preference" or "Willingnesstopay (WTP)" space utility specifications. The program includes an option to run a multistart optimization loop with random starting points in each iteration, which is useful for nonconvex problems like MXL models or models with WTP space utility parameterizations. The main optimization loop uses the nloptr function to minimize the negative loglikelihood function.
