%description
Estimates parameters in Mixture Transition Distribution (MTD) models, a
class of high-order Markov chains. The set of relevant pasts (lags) is
selected using either the Bayesian Information Criterion or the Forward
Stepwise and Cut algorithms. Other model parameters (e.g. transition
probabilities and oscillations) can be estimated via maximum likelihood
estimation or the Expectation-Maximization algorithm. Additionally,
'hdMTD' includes a perfect sampling algorithm that generates samples of an
MTD model from its invariant distribution. For theory, see Ost & Takahashi
(2023) <http://jmlr.org/papers/v24/22-0266.html>.
