I can see that by using the syntax I can get the AIC for multiple regression analysis, however, I would like it to report the corrected AIC as I have a small sample size. I can see that such a corrected AIC can be reported when using the generalized linear model option. As such can this be accessed for regression analysis?

Why not just use GENLIN with a linear model, since it give you the AICC? Or use LINEAR, which labels it just Informtion Criterion but it is the AICC.

Both are available under Analyze > Generalized Linear Models or Analyze > Regression > Automatic Linear Modeling (turn off the automatic data prep), respectively.

Hi Jon,

Thanks for the advice, does the GENLIN function allow hierarchical multiple regression? I want to use the AICc to compare different regression models with different combinations of predictors .

It sounds like you mean just entry of blocks of variables. You would have to do that manually with GENLIN. LINEAR will enter variables in importance order using forward stepwise or another selection method. It shows you the model variables and the AICC for each step and the AICC, but it only shows the coefficients from the last step, so you would have to back up if you want to see coefficients from intermediate equations.
