FLXMCdist1

FlexMix Clustering of Univariate Distributions

Description

These are drivers for flexmix implementing model-based clustering of univariate data using different distributions for the component-specific models.

Usage

FLXMCdist1(formula = . ~ ., dist, ...)

Arguments

`formula`	A formula which is interpreted relative to the formula specified in the call to `flexmix` using `update.formula`. Only the left-hand side (response) of the formula is used. Default is to use the original `flexmix` model formula.
`dist`	Character string indicating the component-specific univariate distribution.
`...`	Arguments for the specific model drivers.

Details

Currently drivers for the following distributions are available:

Lognormal ("lnorm")
inverse Gaussian ("invGauss" using dinvGauss)
gamma ("gamma")
exponential ("exp")
Weibull ("weibull")
Burr ("burr" using dburr)
Inverse Burr ("invburr" using dinvburr)

Value

FLXMCdist1 returns an object of class FLXMC.
