## Aicc

While using SAS to fit a longitudinal study with unstructured covariance model. I have the following information criterion output:

-2log likelihood (l)= 504.8

AIC=524.8

AICC=528.2

BIC=534.7

AIC=l+2k=504.8+2(10)=524.8

BIC=l+klog(N)=504.8+10log(20)=534.7

How can find AICC? The formula that I tried is AICC=l+ \frac{2Nk}{N-k-1} but it don't seem to work

By the way, what happen to the previous latex input? it don't seem to work for me now?
