model comparison

[Miracle]

Hi everyone.

I have done some reading about halving the p-value (difference in -2LL) when comparing 2 different models produced by proc mixed. Is it more appropriate this way?

Your advice is greatly appreciated. Have a great day.

Check the AIC values( Akaike's Information Criteria) when comparing between models using PROC MIXED. The model with a smaller value of AIC is a better fit of the data
