%description
Models categorical time series through a Markov Chain when a) covariates
are predictors for transitioning into the next state/symbol and b) when
the dependence in the past states has variable length. The probability of
transitioning to the next state in the Markov Chain is defined by a
multinomial regression whose parameters depend on the past states of the
chain and, moreover, the number of states in the past needed to predict
the next state also depends on the observed states themselves. See Zambom,
Kim, and Garcia (2022) <doi:10.1111/jtsa.12615>.
