R Documentation

A toolkit which computes a selection of model adequacy tests `LCTMtoolkit`

Description

The function LCTMtoolkit computes a selection of model adequacy tests, including the APPA (average posterior probability of assignment), the OCC (odds of correct classification), entropy E, Relative entropy (E_k), odds of correct classification is the ratio of the odds of classification based on the maximum posterior probablity classification rule and the estimated class membership proportions (pi_k)

Usage

LCTMtoolkit(model)

Arguments

model

the models to be compared which is the output from hlme() R model or model is the output of SASmodelbuilder(oe, os, op, of) passed through it

Value

A selection of model adequacy tests, including the APPA (average posterior probability of assignment), the OCC (odds of correct classification), entropy $E$, Relative entropy ($E_k$),
