How to check & interpret an MCMCglmm ordinal model in R?
I'm trying to explain changes in tree vitality from 1 to 3 (1=green, 2=damage, 3=dry) using precipitation, diameter and tree species in an MCMCglmm model. I am struggling with two questions:1. How do I check if the model is correct? 2. How do I interpret the summary of the MCMCglmm model in relation to my response variable (the three groups 1,2 and 3)?
