A function to simulate a discrete time Markov chain.
This function simulates a discrete time Markov chain with transition matrix P, state space 0,1,..,n and and initial state i for nsteps transitions.
MCSimulation(P,i,nsteps)
P
: the transition matrix.i
: the initial state.nsteps
: the number of transitions to be simulated.We assume that P is well defined transition matrix with rows summing to 1.
Returns the vector statehist containing the realisation of the chain for nsteps transitions.\
