FLXMRnlm: flexmixNL Interface for Generalized Nonlinear Models

Description

This is the main driver for flexmixNL interfacing the family of Generalized Nonlinear Models.

Usage

FLXMRnlm(formula = . ~ ., 
         family = c("gaussian", "Gamma"), 
         start = list(), 
         offset = NULL)

Arguments

formula

A model formula decribing the nonlinear predictor and including variables and regression parameters.

family

A character string naming a family function (family="gaussian" or family="Gamma" available).

start

A list of starting values for the regression parameters.

offset

Specification of an a priori known component to be included in the nonlinear predictor during fitting.

Value

Returns an object of class FLXMRnlm.

Details

Models for FLXMRnlm are specified by a model formula (formula argument) relating the response to a nonlinear predictor. When fitting normal mixture models (family="gaussian") the nonlinear predictor is explicitely formulated (see also nls). When fitting gamma mixture models (family="Gamma") the nonlinear predictor is specified by a symbolic description (see also gnm).

Variables not included in the data frame (see also flexmix) are identified as the regression parameters. Starting values are required for every regression parameter.

See flexmixNL for examples.
