abstract: Implements the three-step workflow from Frings (2026, working paper) for
  specifying latent class multinomial logit (LCMNL) models. The maximum-likelihood
  multi-start is initialised from six clusterings of respondents' revealed-preference
  signatures (k-means, Gaussian mixture, hierarchical clustering with Ward, complete,
  and average linkage, and partitioning around medoids); LCMNL is estimated across
  a user-specified range of class counts; and a mixed multinomial logit (MMNL) benchmark
  is reported alongside BIC, AIC, ICL, and a classification-entropy diagnostic. Accepts
  long- or wide-format discrete-choice data with optional availability columns. Validated
  against five public reference datasets (Vittel, Apollo mode and route choice, Electricity,
  Swissmetro). Wraps the 'apollo' package for maximum-likelihood estimation.
