# Deviance information criterion

DIC is the ‘Deviance Information Criterion’, and is given byDIC = Dbar + pD = Dhat + 2 pD. The model with the smallest DIC is estimated to be the model that would best predict a replicate dataset which has the same structure as that currently observed. Return to the top What is the connection between DIC and AIC?.

The main objective of this paper is to demonstrate that model selection within the class of SV models is better performed using the **deviance** **information** **criterion** (DIC).

Model selection is the task of choosing a model from a set of potential models with the best inductive bias, which in practice means selecting parameters in an attempt to create a model of optimal complexity given (finite) training data. "Thus learning is not possible without inductive bias, and now the question is how to choose the right bias. Recall that the regression equation (for simple linear regression) is: y i = b 0 + b 1 x i + ϵ i. Additionally, we make the assumption that. ϵ i ∼ N ( 0, σ 2) which says that the residuals are normally distributed with a mean centered around zero.

Bayes Rule. The cornerstone of the Bayesian approach (and the source of its name) is the conditional likelihood theorem known as Bayes' rule. In its simplest form, Bayes' Rule states that for two events and A and B (with P ( B) ≠ 0 ): P ( A | B) = P ( B | A) P ( A) P ( B) Or, if A can take on multiple values, we have the extended form:.

Bayesian approaches for **criterion** based selection include the marginal likelihood based highest posterior model (HPM) and the **deviance** **information** **criterion** (DIC).
