Calculates the second-order corrected Akaike Information Criterion for objects of class pcrfit
, nls
, lm
, glm
or any other models from which coefficients
and residuals
can be extracted. This is a modified version of the original AIC which compensates for bias with small n. As qPCR data usually has \frac{n}{k} < 40 (see original reference), AICc was implemented to correct for this.

Extends the AIC such that
AICc = AIC+\frac{2k(k + 1)}{n - k - 1}
with k = number of parameters, and n = number of observations. For large n, AICc converges to AIC.
The second-order corrected AIC value.
