llratio {depmixS4}R Documentation

Log likelihood ratio test on two fitted models

Description

Performs a log likelihood ratio test on two fitted depmix models.

Usage

        
        llratio(basemodel, constrainedmodel, ...)
        

Arguments

basemodel Fitted model with a logLik method.
constrainedmodel Fitted model with a logLik method.
... Not currently used.

Value

llratio returns an object of class llratio which has slots:

value : Minus twice the loglikelihood difference.
df : The degrees of freedom, ie the difference in number of freely estimated paraemters between the models.


The print method shows the value, the degrees of freedom and the corresponding p-value under the chisquared distribution.
