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 WebMar 26, 2024 · The Akaike information criterion is calculated from the maximum log-likelihood of the model and the number of parameters (K) used to reach that likelihood. The AIC function is 2K – 2 (log-likelihood). Lower AIC values indicate a better-fit model, and a model with a delta-AIC (the difference between the two AIC values being compared) of …
