I have two equations for the calculation of AIC:
AIC = 2k + n[ln(2*pi*RSS/n) +1]
AIC = 2k + n[ln(RSS/n)]
Which of these, if any, can be used to compare models that have
different values of n (as well as different values of k) ?
If neither can be used for models with different values of n, can you
suggest the correct equation.
many thanks indeed
