rmix: Random Deviates from EMMIX Models

In suren-rathnayake/EMMIXmfa: Mixture Models with Component-Wise Factor Analyzers

Description

Random number generator for emmix models.

Usage

rmix(n, model, ...)

Arguments

model	An object of class 'emmix' containing a mode of mfa, mcfa, mtfa, or mctfa.
n	Number of sample to generate.
...	Not used.

Details

This function uses rmvnorm and rmvt functions from the mvtnorm package to generate samples from the mixture components.

Algorithm works by first drawing a component based on the mixture proprotion in the model, and then drawing a sample from the component distribution.

Value

A numeric matrix with samples drawn in rows.

Examples

set.seed(1)
model <- mcfa(iris[, -5], g=3, q=2, nkmeans=1, nrandom=1, itmax = 25)
dat <- rmix(n = 10, model = model)
