See references. Burnham and Anderson (2002). This correction to the AIC is
derived under some assumption of normality, so it's validity may depend on
there being large counts for each capture pattern so that the multivariate
normal approximation to the multinomial is good.The AIC methods for VGAM purport to have the AICc option for the
vglm
, but this did not seem to exist for the vgam
as of
