In flexmix: Flexible Mixture Modeling

Simultaneous Inference in Finite Mixtures of Regression Models

Description

Extracts coefficient estimates and their covariance estimate to perform tests for zero coefficients or constant effects re-using functionality from package multcomp.

Usage

flxglht(model, linfct, ...)
## S4 method for signature 'flexmix,character'
flxglht(model, linfct, ...)
## S4 method for signature 'FLXRoptim,character'
flxglht(model, linfct, ...)

Arguments

model	Either a fitted mixture model of class "flexmix" or a re-fitted mixture model of class "FLXRoptim".
linfct	A character string which can be either "zero" or "tukey".
...	Currently not used.

Details

Only tested for finite mixture models fitted with driver FLXMRglm.

Value

An object of class "glht".
