TCM Conference 2016 Chris Gann ganncncssmedu A taxi company has divided the city into three regions Northside Downtown and Southside By keeping track of pickups and deliveries the company has found that of the fares picked up in Northside 50 stay in that region 20 are taken Downtown and 30 go to Southside Of the fares picked up Downtown only 10 go to Northside 40 stay Downtown and 50 go to Southside Of the fares picked up in Southside 30 go to each of Northside and Downtown while 40 stay in Southside . The fundamental condition required is that for each pair of states ij the longrun rate at which the chain makes a transition from state to state equals the longrun rate at which the chain makes a transition from state to state ij ji 11 Twosided stat Alan Ritter.

Markov processes in continuous time were discovered long before Andrey Markov's work in the early 20th . centuryin. the form of the Poisson process.. Markov was interested in studying an extension of independent random sequences, motivated by a disagreement with Pavel Nekrasov who claimed independence was necessary for the weak law of large numbers to hold..
