EBIC: Extended Bayesian Information Criterion

In pboost: Profile Boosting Framework for Parametric Models

Extended Bayesian Information Criterion

Description

The Extended BIC possesses the selection consistency in high-dimensional model.

It can be called by the fitted model that has standard logLik method to access the attributes nobs and df, such as lm, glm.

Usage

EBIC(object, p, p.keep, ...)

Arguments

object	Fitted model object.
p	Total number of candidate features, which is available in pboost.
p.keep	Number of features that are pre-specified to be kept in model.
...	Additional parameters, which is available in pboost.

Details

The extended BIC (EBIC) is defined as

EBIC(obj) = BIC(obj) + 2 * r * log(choose(p - |p.keep|, df - |p.keep|)).

Value

A function to obtain the EBIC value of a fitted object.
