WebFirst-passage-time moments of Markov processes 941 The fundamental matrix of the original continuous-time Markov chain is similarly defined (refer to Keilson [4], ?7.1): Z = … WebFIRST-PASSAGE-TIME MOMENTS OF MARKOV PROCESSES DAVID D. YAO,* Columbia University Abstract We consider the first-passage times of continuous-time Markov chains. Based on the approach of generalized inverse, moments of all orders are derived and expressed in simple, explicit forms in terms of the 'fundamental matrix'. The
