R Documentation

Extract parameters for certain components from mclust

Description

Extracts parameters of certain mixture components from the output of summary.mclustBIC and updates proportions so that they sum up to 1.

Usage

  extract.mixturepars(mclustsum,compnumbers,noise=FALSE)

Arguments

`mclustsum`	output object of `summary.mclustBIC`.
`compnumbers`	vector of integers. Numbers of mixture components.
`noise`	logical. Should be `TRUE` if a noise component was fitted by `mclustBIC`.

Value

Object as component parameters of summary.mclustBIC-output, but for specified components only. (Orientation information from all components is kept.)

Examples

  set.seed(98765)
  require(mclust)
  iriss <- iris[sample(150,20),-5]
  irisBIC <- mclustBIC(iriss,G=5,modelNames="VEV")
  siris <- summary(irisBIC,iriss)
  emp <- extract.mixturepars(siris,2)
  emp$pro
  round(emp$mean,digits=1)
  emp$variance$modelName
  round(emp$variance$scale,digits=2)
