abstract: 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) <https://doi.org/10.1017/CBO9780511805271>.
