%description
Fast estimation of multinomial (MNL) and mixed logit (MXL) models in R.
Models can be estimated using "Preference" space or "Willingness-to-pay"
(WTP) space utility parameterizations. Weighted models can also be
estimated. An option is available to run a parallelized multistart
optimization loop with random starting points in each iteration, which is
useful for non-convex problems like MXL models or models with WTP space
utility parameterizations. The main optimization loop uses the 'nloptr'
package to minimize the negative log-likelihood function. Additional
functions are available for computing and comparing WTP from both
preference space and WTP space models and for predicting expected choices
and choice probabilities for sets of alternatives based on an estimated
model. Mixed logit models can include uncorrelated or correlated
heterogeneity covariances and are estimated using maximum simulated
likelihood based on the algorithms in Train (2009)
