How to get AIC from Conway–Maxwell-Poisson regression via COM-poisson package in R?
Question
Is there an easy way to get AIC for a Conway–Maxwell-Poisson regression from COM-poisson package in R?
see http://cran.r-project.org/web/packages/COMPoissonReg/COMPoissonReg.pdf
I am not able to find build in loglik function nor AIC
Shall I use AIC(glm of poisson fit) - chisq(cmp_fit) + 2 ?

I figured out myself.
cmp calls ComputeBetasAndNuHat which returns a list which has objective as minusloglik
So I can change the function cmp to get this value.
