Data is # of individuals through time. I fit logistic and exponential growth curves to the data. And event (population bottleneck) takes # to nearly zero at one point. The growth curves are fit in parts: one on either side of the event.

How do I calculate the "total" AIC for the two curves which describe the entire population history? I assume it is not simply adding the AIC scores you can get from each piece separately.

AIC scores for a curve fit in two parts

Data is # of individuals through time. I fit logistic and exponential growth curves to the data. And event (population bottleneck) takes # to nearly zero at one point. The growth curves are fit in parts: one on either side of the event.
