hello fellow BUGS users/misusers,
I'm running a mark-recapture analysis on some wildlife data. For this
purpose I used and modified code used by Gimenez et al for what I want
to do is similar in the first instance.
I am looking to estimate survival (phi) and capture (p) probabilities
and I want these to be year-specific (as oppposed to constant). If I run
the model using constant phi and p, model runs ok. If I then run model
allowing for year-specific phi, again model runs ok. However, if I
include in addition, year-specific values for p, the model fails and I
get the message "elements of proportion vector of multinomial y[1,1]
must sum to unity".
"y" is the label for my data.
I've tried various strategies, but without success. If anyone has
experience with this kind of analysis (or if not!) and can advise, I'd
be most grateful. Can send code and data on request.
regards,
Neil
