%description
Fit the reduced-rank multinomial logistic regression model for Markov
chains developed by Wang, Abner, Fardo, Schmitt, Jicha, Eldik and Kryscio
(2021)<doi:10.1002/sim.8923> in R. It combines the ideas of multinomial
logistic regression in Markov chains and reduced-rank. It is very useful
in a study where multi-states model is assumed and each transition among
the states is controlled by a series of covariates. The key advantage is
to reduce the number of parameters to be estimated. The final coefficients
for all the covariates and the p-values for the interested covariates will
be reported. The p-values for the whole coefficient matrix can be
calculated by two bootstrap methods.
