Compute the stationary distribution of a continuous-time Markov chain

A well-behaved continuous-time Markov chain converges to a unique stationary distribution, here called \(\pi\). This distribution satisfies $$\pi Q = 0,$$ subject to \(\sum_{j=1}^N \pi_j = 1\), where \(Q\) is the infinitesimal generator of the Markov chain. This function solves the linear system of equations above for a given generator matrix.

Usage

stationary_cont(Q)

Arguments

Q

infinitesimal generator matrix of dimension c(N,N)

Value

stationary distribution of the continuous-time Markov chain with given generator matrix

Q = generator(c(-2,-2))
Pi = stationary_cont(Q)
