• TITLE: A Closed Form Probability Mass Function for Occupation Times in a Three-State Markov Chain

  KEYWORDS: Occupation Times, Markov Chains, Probability Generating Functions, Probability Mass Function

  ABSTRACT: We obtain a closed form expression for the joint probability mass function of the occupation times for a Three-State Markov chain. Our representation extends the long-standing result for a Two-State Markov chain by utilizing the method of probability generating functions given in Pedler.
