I need to use the glmmPQL function for an assignment, but when I call for the summary of the function, it gives the AIC a value of NA. How do I get R to give me the AIC value?
You did! Hint: have you read the reference of which this is part of the support software? If so you will know that you need a maximized likelihood to evaluate AIC, and your fit is not an MLE.
