Hi everyone, I just did a GLM binomial regression. I am wondering how do I know when my responses are fixed? I have found that an interaction between two factors is the most significant predictor amongst other factors by comparing the AIC and add1 with each factor. Does this mean that the interaction between these two factors are my fixed responses? I would like to do a quasibinomial afterwards.
