WHAT ARE THE DISAdvantages of using AIC Akaike Information C

WHAT ARE THE DISAdvantages of using

AIC: Akaike Information Criterion

AICc: The corrected Akaike information criterion

Solution

if all the candidate models have the same k, then AICc and AIC will give identical (relative) valuations; hence, there will no disadvantage in using AIC instead of AICc. Furthermore, if n is many times larger than k², then the correction will be negligible; hence, there will be negligible disadvantage in using AIC instead of AICc.
