dealWithLabelSwitching {BayesBinMix}

Label switching algorithms

Description

This is a wrapper for the label.switching package. It is used to post-process the generated MCMC sample in order to undo the label switching problem. This function is called internally to the coupledMetropolis command.

Usage

dealWithLabelSwitching(outDir, reorderModels, binaryData, z.true)

Arguments

outDir

The directory where the output of coupledMetropolis was previously produced.

reorderModels

Boolean value indicating whether to reorder the MCMC corresponding to each distinct generated value of number of clusters or not.

binaryData

The input data.

z.true

An optional vector of cluster assignments considered as the ground-truth clustering of the observations. Useful for simulations.

Details

See the label.switching package.
