hmflatprobit {bayess}

Metropolis-Hastings for the probit model under a flat prior

Description

This random walk Metropolis-Hastings algorithm takes advantage of the availability of the maximum likelihood estimator (available via the glm function) to center and scale the random walk in an efficient manner.

Usage

hmflatprobit(niter, y, X, scale)

Arguments

niter

number of iterations

y

binary response variable

X

covariates

scale

scale of the random walk

Value

The function produces a sample of \beta's of size niter.
