Apply Relabelling Scheme to bmoe

apply_relabelling.Rd

Allows swapping of component labels, per MCMC iteration, to mitigate label switching.

Usage

apply_relabelling(object, permutations = NULL)

# S3 method for bmoe_fit
apply_relabelling(object, permutations = NULL)

table_permutations(permutations)

Arguments

object

Object that inherits from bmoe_fit.

permutations

list. See Permutations section.

Value

bmoe_fit object with switched labels.

Functions

  • table_permutations(): Calculate summary of a permutations object.

Permutations

Permutations are stored in a list where \(i^{th}\) elements corresponds to the \(i^{th}\) chain.

Each element is a matrix with one permutation per row for each iteration. Note that

  • A vector can be supplied to apply the same scheme to all MCMC output.

  • A matrix can be supplied to apply the same relabelling to all chains.

  • NULL can be supplied to use boys_henderson_2002().

A permutation of c(3, 1, 2) denotes relabelling of

  • 1 -> 3

  • 2 -> 1

  • 3 -> 2
