Bayesian regression model selection using G priors

Description

Using Zellner's G priors, computes the log marginal density for all possible regression models

Usage

bayes.model.selection(y, X, c, constant=TRUE)

Arguments

y vector of response values
X matrix of covariates
c parameter of the G prior
constant logical variable indicating if a constant term is in the matrix X

Value

mod.prob matrix specifying the model and the associated value of the log marginal density
converge logical vector indicating if the laplace algorithm converged for each model

Examples

data(birdextinct)
logtime=log(birdextinct$time)
X=cbind(1,birdextinct$nesting,birdextinct$size,birdextinct$status)
bayes.model.selection(logtime,X,100)
