Calculates the Akaike Information Criterion for objects of class oglmx
. Calculate using the formula -2*loglikelihood + k*npar where npar represents the number of parameters in the model and k is the cost of additional parameters, equal to 2 for the AIC, it is k=\log(n) with n the number of observations for the BIC.
