❝ Do you think that we need to take the absolute value for AIC (extractAIC) here? :confused: AICs can be negative and the smallest is the best, as far as I can remember. I know that these codes were written by Ace previously. What do you think about this?

❝ return(cbind((nrow(dat)-m+1),abs(extractAIC(lm(log(conc)~time,dat[m:nrow(dat),])))[2],summary(lm(log(conc)~time,dat[m:nrow(dat),]))$adj.r.squared))


Maybe a bit of clarification for the abs() value:
I took the example from a thread, mentioned before, and get the same AIC values, except that they were negative. So that's the reason why I used the abs() value.

The epistemological value of probability theory is based on the fact
that chance phenomena, considered collectively and on a grand scale,
create non-random regularity.    Andrey Kolmogorov
