The definition of\nparametric and non-parametric model specifications is also\npossible. Furthermore, three different types of drifting\nsemi-Markov models are considered. These models differ in the\nnumber of transition matrices and sojourn time distributions\nused for the computation of a number of semi-Markov kernels,\nwhich in turn characterize the drifting semi-Markov kernel. For\nthe parametric model estimation and specification, several\ndiscrete distributions are considered for the sojourn times:\nUniform, Poisson, Geometric, Discrete Weibull and Negative\nBinomial. The non-parametric model specification makes no\nassumptions about the shape of the sojourn time distributions.\nSemi-Markov models are described in: Barbu, V.S., Limnios, N.\n(2008) . Drifting Markov models\nare described in: Vergne, N. (2008)\n. Reliability indicators of\nDrifting Markov models are described in: Barbu, V. S., Vergne,\nN. (2019) .
