%description
Description: Functions and S4 classes to create, manage and analyse
discrete time Markov chains. Includes probabilistic analysis of chain
structure (state classification, hitting times, stationary distributions,
spectral and mixing diagnostics), statistical inference (maximum
likelihood and Bayesian estimation, tests of the Markov property,
homogeneity, stationarity and order, simulation), higher-order and
multivariate chains, state aggregation, and import/export to JSON, YAML
and CSV. Basic support for continuous time Markov chains is also provided;
some of these functions depend on the suggested 'ctmcd' package. See
Spedicato (2017) <doi:10.32614/RJ-2017-036>.
