For the Markov process with transition diagram shown
at right, say why you would expect the steady state to
have equal probabilities for the four states A, B,C, D,
no matter what the probabilities r, s and t happen to
be. [As is the normal convention, missing arrows all
represent transitions with probability zero.]
Write out the transition
matrix T for this process:
Use T" to confirm the steady state vector implied by part (a).
For r= 0.2, s= 0.5 and t= 0.3 how many time steps are needed to arrive at the
steady state, to 2 decimal places accuracy, starting from any initial state vector?
[Hint: Use a matrix calculator to take powers of T" as in Q2(a).]
