batchmix (version 2.2.1)

plotSampledBatchScales: Plot sampled batch scales

Description

Plot the sampled values for the batch scale in each dimension from the output of the mixture model functions. Not recommended for large B or P.

Usage

plotSampledBatchScales(samples, burn_in = 0)

Value

A ggplot object of the values in each sampled batch mean per iteration.

Arguments

samples

The output of the ``batchUnsupervisedMixtureModel`` or ``batchSemiSupervisedMixtureModel`` functions.

burn_in

The samples at the beginning of the chain to drop. Defaults to 0.

Examples

# Data in matrix format
X <- matrix(c(rnorm(100, 0, 1), rnorm(100, 3, 1)), ncol = 2, byrow = TRUE)

# Observed batches represented by integers
batch_vec <- sample(seq(1, 5), size = 100, replace = TRUE)

# MCMC iterations (this is too low for real use)
R <- 100
thin <- 5

# MCMC samples and BIC vector
samples <- runBatchMix(X, R, thin, batch_vec, "MVN")

# Plot the sampled value of the batch scales against MCMC iteration
plotSampledBatchScales(samples)
