#In this example, we generate 250 observations and 6 states (including death). Based on these observations, we apply the `CreateTrans()` function and generate the transitions.

#Create subject IDs for each observation. In this example, we have 50 subjects and 250 observations in total.

#Create Age variable for each observation.
Age <- rep(31:35, times = 50)
