merge_comp {gmgm}

Merge mixture components of a Gaussian mixture model

Description

This function merges mixture components of a Gaussian mixture model (Zhang et al., 2003).

Usage

merge_comp(gmm, comp = seq_along(gmm$alpha))

Arguments

gmm

An object of class gmm.

comp

An integer vector containing the indexes of the merged mixture components (by default all the components of gmm).

Value

The gmm object after merging the mixture components.
