Hi Phill,
Sorry if I was not clear. My question was toward that, sometimes, these formulas can differ (even slightly) from package to package (either by the signal of likelihood and/or by the penalty term). Concerning the statistics, from the EM frequentist approach, I supposed that they are:
AIC = -2loglik + 2p
BIC = -2loglik + p log(n)
AICc = AIC + 2p(p+1)/(n-p-1)
SABIC = -2loglik + p log((n+2)/24)
where n is the number of sujects and p is the number of parameters to be estimatted. Concering DIC, I usually consider it within an MCMC context so, I am not sure the exactly way to calcule it using only the punctual estimates provided by the EM bayesian approach.
Many thanks,
Caio
Phil
