Hi John,(not dear john ;-))I don't think you miss anything, maybe we look at the different sides ofa coin. State transition probabilities are a list of 2-d array or amatrix which results from calculation of the probabilities from 1 stateto the others. If we have 4 states, say; 1,2,3,4 , then we have a chanceto go from state 1 or 2 or 3 or 4 to the other 3 states with differentprobabities. It is an analytical tool used in decision making. Mostpeople make decision best on intuition. As I said the other dimension isthe time it takes in each transition. So, if you think about 3 periodsof time, yesterday, today and tomorrow you will get differentprobabilities in each period. If this period is short say a millisecondor less, then human can not take any notice. But, if the time isextended then what will happen in the interval. My want is to keep theseprobabilties in a file appending with new probabilties calculated fornew period. They say that, in long run the state transition probabiltieswill not depend upon the initial states (the beginning ones). Andthinngs may be clear enough to make decision (with no longer waiting).Tawee
