Dear All,
I am trying to understand the way that BIC is calculated for a mixed model using PROC MIXED, I arrived to the AIC reported by SAS under the ML and REML version.
However when i tried manually to calculate the BIC it seems that it is penalized with a function of log(n^2) instead of log(n), being n the number of subjects.
Could somebody iluminate me how SAS calculates BIC under ML and REML?
I am using the currently studio version,
Thanks a lot for your help
Thanks so much for your reply, i had not considered the 2 in the AIC complexity penalty. Best wishes, Johanna
