Homework Help: Regression - AIC/SBC Comparison

  1. Jan 24, 2012 #1
    I'm not sure if this is the right place for this question, but it was on the comparison between different model's AIC/SBC values.

    I ran a linear regression and got an AIC/SBC of .743/.768. When I ran the same regression in log-linear form I ended up with an AIC/SBC of -7.559/-7.534.

    My textbook suggests that the smaller the value, the better the model, but it only compares positive values which seem to tend towards zero.

    My question is this: should I be comparing the absolute values of these (so that the closet to zero is the best) or should I be looking at a strictly greater than scheme in which the more negative, the smaller, and therefore the better?

    Thanks!

    Never mind. I figured out I could estimate the log-linear model in levels which would allow me a comparison that fits with the generic linear regression. I couldn't figure out how to delete the post. Thanks anyways!
