is.dsmm

Checks for the validity of the specified attributes and the
 inheritance of the S3 class <code>dsmm</code>. This class acts like a parent
 class for the classes <code>dsmm_fit_nonparametric,</code>
 <code>dsmm_fit_parametric, dsmm_parametric</code> and <code>dsmm_nonparametric</code>.

Performs parametric and non-parametric estimation and simulation of
drifting semi-Markov processes. The definition of parametric and non-parametric
model specifications is also possible. Furthermore, three different types of
drifting semi-Markov models are considered. These models differ in the number
of transition matrices and sojourn time distributions used for the computation
of a number of semi-Markov kernels, which in turn characterize the drifting
semi-Markov kernel. For the parametric model estimation and specification,
several discrete distributions are considered for the sojourn times: Uniform,
Poisson, Geometric, Discrete Weibull and Negative Binomial. The non-parametric
model specification makes no assumptions about the shape of the sojourn time
distributions. Semi-Markov models are described in:
Barbu, V.S., Limnios, N. (2008) <doi:10.1007/978-0-387-73173-5>.
Drifting Markov models are described in:
Vergne, N. (2008) <doi:10.2202/1544-6115.1326>.
Reliability indicators of Drifting Markov models are described in:
