Now I know i have a few singularities in this model, and it isn't one I would end up using, but what i'm curious about is the fact that there is no beta for the season fall, or for the stratum 2. I get that year 1 is being used an intercept.
So why isn't there a beta for fall or stratum 2? and how are the real parameter estimates for survival in stratum 2 or season fall being made?
Any help understanding this would be much appreciated.
