getKernel: Method to get the semi-Markov kernel q
In smmR: Simulation, Estimation and Reliability of Semi-Markov Models

Computes the semi-Markov kernel q_{ij}(k).

1	getKernel(x, k, var = FALSE, klim = 10000)

`x`	An object of S3 class `smmfit` or `smm`.
`k`	A positive integer giving the time horizon.
`var`	Logical. If `TRUE` the asymptotic variance is computed.
`klim`	Optional. The time horizon used to approximate the series in the computation of the mean sojourn times vector m (cf. meanSojournTimes function) for the asymptotic variance.

An array giving the value of q_{ij}(k) at each time between 0 and k if var = FALSE. If var = TRUE, a list containing the following components:

x: an array giving the value of q_{ij}(k) at each time between 0 and k;
sigma2: an array giving the asymptotic variance of the estimator σ_{q}^{2}(i, j, k).
