%description
Tools for phase-type distributions including the following variants:
continuous, discrete, multivariate, in-homogeneous, right-censored, and
regression. Methods for functional evaluation, simulation and estimation
using the expectation-maximization (EM) algorithm are provided for all
models. The methods of this package are based on the following references.

distributions via the EM algorithm, Olsson, M. (1996). Estimation of
phase-type distributions from censored data, Albrecher, H., & Bladt, M.
