Hi Ben,
In my model, I have set the intercepts for GeneticType so that B isn't
relative to A (using "-1"). There are only 2 levels to GeneticType.
Apologies for the confusion.
The correct model should read:
model<- MCMCglmm(LRS~GeneticType*NAO+
GeneticType *Temp-1,
random = ~Year_of_Spawning,
family = "poisson",
data = data,
verbose = TRUE,
nitt = 1010000, burnin = 1000, thin = 1000)
Regards Temp, it is mean-centred whereas NAO wasn't. I re-ran the model
with a mean-centred NAO variable and it made no difference.
Cheers,
Ronan
