Hello, I am a new Mark user and inquiring about how to best set up a multi-state model with age structure. I have gotten as far as chapter 13 in the Mark book over the past several months but obviously have a long way to go..... In this current study there are 3 states with 2 age classes. I thought maybe about 6 states with each age class having its own 3 states and constraining psi so that the older age class cannot transition to any state of the younger age class. Perhaps 3 states with 2 age groups would work as well but not sure if it would be more or less appropriate. I am sure the best approach is obvious to most here.... so I am hoping for some suggestions.
Thanks for any advice.
