get_IC
calculates the information criteria values AIC, HQIC, and BIC divided by the number of observations.
get_IC(loglik, npars, T_obs)
loglik
: log-likelihood valuenpars
: number of (freely estimated) parameters in the modelT_obs
: numbers of observations with the starting values excluded.Returns a data frame containing the information criteria values divided by the number of observations.
