Hi, I need to fit models and use AIC method to campare the best fitted model
manually.
When i extract AIC by using extractAIC, it gave me the df and AIC values.
Now the problem is, how can I compare the AIC values from two models?
is there anyway to extract AIC with no df so that I can compare directly?
Thank you!
