%description
Fitting (hierarchical) hidden Markov models to financial data via maximum
likelihood estimation. See Oelschläger, L. and Adam, T. "Detecting Bearish
and Bullish Markets in Financial Time Series Using Hierarchical Hidden
Markov Models" (2021, Statistical Modelling)
<doi:10.1177/1471082X211034048> for a reference on the method. A user
guide is provided by the accompanying software paper "fHMM: Hidden Markov
Models for Financial Time Series in R", Oelschläger, L., Adam, T., and
Michels, R. (2024, Journal of Statistical Software)
