FD.aicbic {FlexDir}

Information Criterions of a Flexible Dirichlet Model

Description

Akaike Information Criterion (AIC) and Bayesian Information Criterion (BIC) of a fitted Flexible Dirichlet model. An Information Criterion for one fitted model object for which a log-likelihood value can be obtained is defined as -2*log-likelihood + k*npar, where npar represents the number of parameters in the fitted model, and k = 2 for AIC, or k = log(n) for BIC ( n being the number of observations).

Usage

FD.aicbic(x)

Arguments
