WebAIC only handles unknown scale and uses the formula n log (RSS/n) - n + n log 2π - sum log w where w are the weights. For glm fits the family's aic () function to compute the AIC: see the note under logLik about the assumptions this makes. k = 2 corresponds to the traditional AIC, using k = log (n) provides the BIC (Bayesian IC) instead. Value WebThe criterion used is. AIC = - 2\log L + k \times \mbox {edf}, AI C = −2logL+k ×\mboxedf, where L L is the likelihood and edf the equivalent degrees of freedom (i.e., the number of free parameters for usual parametric models) of fit .
