Hi,
This is the first time that I have posted here. I have reviewed all of the help documents and the MARK book, but I can't seem to find anything that addresses the issue that I am having.
I have been using MARK for the last couple of years, but our models are getting increasingly complex. Here's the model that we ran: {Psi(y1=y2, Gy3, Uy3)gam(G1=U1, G2, U2))p(y1(G,Ut)y2(Unt)y3(Unt))}. There are two management units, G and U. We have three years' of data. The goal of the model is to keep Psi constant across units in years 1 and 2, but allow it to change in year 3 by unit. The same for gamma. I'm not sure if this helps, but I have coded this model in the following way into the PIM:
Occupancy of G y1-3: 112
Occupancy of U y1-3:113
Gamma G:45
Gamma U:46
The other 7 parameters are coded for detection.
As the PIM indicates, the first three parameters are taken up by Psi, while the next three are Gamma.
But, when I run the model, here's what I get from MARK:
Index Label Estimate
1 Psi 0.25
2 Psi 0.43
3 Gamma 0.25
4 Gamma 0.05
5 Gamma 0.24
6 Gamma 0.05
The labels on all the detection probability parameters are also correct.
We have tried this model on several different species and get the same (what I perceive as a) mis-application of labels on all of them. What am I missing?
Thank you very much for your time.
