%description
Fit mixture of Markov chains of higher orders from multiple sequences. It
is also compatible with ordinary 1-component, 1-order or single-sequence
Markov chains. Various utility functions are provided to derive transition
patterns, transition probabilities per component and component priors. In
addition, print(), predict() and component extracting/replacing methods
are also defined as a convention of mixture models.
