dear martin,

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?

Thanks.

❝ 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))
