Multivariate Markov Chains

Provides routines to estimate the Mixture Transition Distribution Model based on Raftery (1985) < http://www.jstor.org/stable/2345788> and Nicolau (2014) specifications, for multivariate data. Additionally, provides a function for the estimation of a new model for multivariate non-homogeneous Markov chains. This new specification, Generalized Multivariate Markov Chains (GMMC) was proposed by Carolina Vasconcelos and Bruno Damasio and considers (continuous or discrete) covariates exogenous to the Markov chain.
