2 time dependend states and probability transition matrix
...ave got anybody experience or a starting point for me, how i can program a function which calculate me a probability transition matrix with a data.frame and two states. I have some independend variable and a class variable for two states - in example one from Jan2003 and the same variables from June2003. Now i would like to calculate the probability that PERSON X change from classA to classB between this time-period dependend from the independend variables. Until now i think about an "easy" function what use the Bayes-Theorem, but it's too bad that i'm not a mathematican....
