I'm using the dynamic two species model in R and estimates I get for gamma and epsilon AB/Ab are identical to each other despite including the INT_Ab term, even when using the code available in the help file.
Help file code:
## fit some multi-season, 2-species models (using different data)
mod0<-occMod(model=list(psi=psi~SP+INT,
gamma =gamma~SP+INT_Ab+INT_Ba+INT_B_a+INT_Baa, epsilon=epsilon~SP+INT_Ab+INT_Ba+INT_B_a+INT_Baa,
p =p~SP+INT_o+INT_d+SP:INT_o),
data=bearcoy,type="do.2sp.1")
Any ideas?
