Some passage-time generating functions for discrete-time and continuous-time finite Markov chains
J. N. Darroch, K. W. Morris · Journal of Applied Probability · 1967
Let T denote a subset of the possible transitions between the states of a finite Markov chain and let Yk denote the time of the kth occurrence of a T-transition. Formulae are derived for the generating functions of Yk, of Yj + k — Yj and of Yj + k — Yj in the limit as j → ∞, for both discrete-time and continuoustime chains. Several particular cases are briefly discussed.
