my question is as follows:
Long & Freese go over this in their book if you happen to have access to
it. Very quickly,
1.what dose D(66) means?and what it tells us?
D = Deviance = -2 * Log-Lik Full Model. The 66 is the DF - # of parameters
(Looks like you have 69 cases and 2 IVs.)
2.as we knows,aic and bic tell us how to choose the best model.the model
with small aic and bic is the better one.but what is the use of aic*n?and
what is bic'?how to caculate it?and what does it tell us ?
AIC*n is, literally, AIC * N. In your case, 18.575 * 69 = 1281.675 (the
slight difference is rounding error). Long and Freese say some people
report this instead of AIC.
BIC' is an alternative version of BIC. The more negative, the better.
thank you!
