The critical difference between AIC and BIC (and their variants) is the asymptotic property under well-specified and misspecified model classes. [28] Their fundamental differences have been well-studied in regression variable selection and autoregression order selection [29] problems. In general, if the goal is prediction, AIC and leave-one-out ...
In statistics, the Bayesian information criterion (BIC) or Schwarz information criterion (also SIC, SBC, SBIC) is a criterion for model selection among a finite set of models; models with lower BIC are generally preferred. It is based, in part, on the likelihood function and it is closely related to the Akaike information criterion (AIC).
The most commonly used information criteria are (i) the Akaike information criterion and (ii) the Bayes factor and/or the Bayesian information criterion (which to some extent approximates the Bayes factor), see Stoica & Selen (2004) for a review. Akaike information criterion (AIC), a measure of the goodness fit of an estimated statistical model
In statistics, the Widely Applicable Information Criterion (WAIC), also known as Watanabe–Akaike information criterion, is the generalized version of the Akaike information criterion (AIC) onto singular statistical models. [1] It is used as measure how well will model predict data it wasn't trained on.
They also note that HQC, like BIC, but unlike AIC, is not an estimator of Kullback–Leibler divergence. Claeskens & Hjort (2008, ch. 4) note that HQC, like BIC, but unlike AIC, is not asymptotically efficient ; however, it misses the optimal estimation rate by a very small ln ( ln ( n ) ) {\displaystyle \ln(\ln(n))} factor.
A 20-pound chandelier that hung in the RMS Titanic has arrived at the Liberty Science Center in Jersey City, New Jersey, after spending decades sitting on the bottom of the Atlantic.
An alternative model selection method is the Akaike information criterion (AIC), formally an estimate of the Kullback–Leibler divergence between the true model and the model being tested. It can be interpreted as a likelihood estimate with a correction factor to penalize overparameterized models. [ 32 ]
