AIC consistency with S-PLUS
Hello-
I understand that log-likelihoods are bound to differ by constants, but if i estimate AIC for a set of simple nested linear models using the following 4 methods, shouldn't at least two of them produce the same ordering of models?
in R:
extractAIC
AIC
in S-PLUS:
AIC
n*log(deviance(mymodel)/n) + 2*p
I find it troubling that these methods all give me different answers as to the best

Any user can have a private library on S-PLUS, and in the same way on R.
See V&R3 p.470 for S-PLUS (and set R_LIBS on R). You need no special
privileges to install library sections or packages, so this should be an
option....
