drawSamplesByTime: Draw samples from a MCMC sampler, by time.

In rjbgoudie/structmcmc: Structural inference for Bayesian Networks and Variable Selection.

Description

Draws samples from an MCMC sampler for a specified number of seconds.

Usage

  drawSamplesByTime(sampler, time, burnin, burninleft,
    thin, verbose, samplesIncrement = 10000)

Arguments

sampler	A sampler object
time	The number of seconds to spend drawing samples.
burnin	The number of samples to discard from the beginning of the sample (includes previous runs)
burninleft	The number of samples still to be discarded.
thin	The frequency with which samples should be kept. eg for thin = 3, every third sample will be kept.
verbose	A logical. Should a progress bar be displayed?
samplesIncrement	The size by which the samples should be incremented.

Examples

set.seed(310)
x1 <- factor(c(1, 1, 0, 1))
x2 <- factor(c(0, 1, 0, 1))
dat <- data.frame(x1 = x1, x2 = x2)

prior <- function(net) 1
initial <- bn(c(), c())

sampler <- BNSampler(dat, initial, prior)
samples <- draw(sampler, time = 15)
