groupmoments-class: Finmix 'groupmoments' class

In simonsays1980/finmix: An R package for Bayesian estimation of finite mixture distributions

Description

Stores moments for finite mixture component distributions. These are only available, if the data contains in addition to observations also indicators defining to which component a certain observation belongs. These indicators are stored in an fdata object in the slot S.

Slots

NK

An array containing the group sizes for each component.

mean

A matrix containing the group averages for each component.

WK

An array containing the within-group variability. For multivariate data this is an array of dimension K x r x r and for univariate data this is simply an array of dimension 1 x K.

var

An array containing the within-group (co)variance. For multivariate data this is an array of dimension K x r x r and for univariate data this is simply an array of dimension 1 x K.

fdata

An fdata object containing the data.
