blinreg: Simulation from Bayesian linear regression model

Description

Gives a simulated sample from the joint posterior distribution of the regression vector and the error standard deviation for a linear regression model with a noninformative or g prior.

Usage

blinreg(y,X,m,prior=NULL)

Arguments

y

vector of responses

X

design matrix

m

number of simulations desired

prior

list with components c0 and beta0 of Zellner's g prior

Value

beta

matrix of simulated draws of beta where each row corresponds to one draw

sigma

vector of simulated draws of the error standard deviation
