rflexmix: Random Number Generator for Finite Mixtures

In flexmix: Flexible Mixture Modeling

Random Number Generator for Finite Mixtures

Description

Given a finite mixture model generate random numbers from it.

Usage

rflexmix(object, newdata, ...)

Arguments

object	A fitted finite mixture model of class flexmix or an unfitted of class FLXdist.
newdata	Optionally, a data frame in which to look for variables with which to predict or an integer specifying the number of random draws for model-based clustering. If omitted, the data to which the model was fitted is used.
...	Further arguments to be passed to or from methods.

Details

rflexmix provides the creation of the model matrix for new data and the sampling of the cluster memberships. The sampling of the component distributions given the classification is done by calling rFLXM. This step has to be provided for the different model classes.

Value

A list with components

y	Random sample
group	Grouping factor
class	Class membership
