Does anyone know how to program mover stayer models in R? They are a type of Markov chain model where there is a group of people who stays in the same place, a group who always moves, and a group who does both. Thanks. Leanne Sanders sanders.486@osu.edu [[alternative HTML version deleted]]

...of diagnoses on the same patient over a sequence of time. The diagnoses are coded 1,2,3,4,5, but could come in a sequence like 1,3,2,5,3,5,...etc. Is there a simple way to count the number of times a 1 diagnosis is followed by a 2, or a 3, ... A 2 by a 1, or 3,....etc. It's almost like a mover-stayer problem. I think. I know this seems simple but any help would be appreciated. Cheers, Calvin -- ==================== Calvin L.
