extract.mixturepars: 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)

Value

Object as component parameters of

summary.mclustBIC-output, but for specified components only. (Orientation information from all components is kept.)

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.

Examples

Run this code
  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)
