BMRMM (version 1.0.0)

model.selection.scores: Model Selection Scores for the Number of Components for Duration Times

Description

Provides the LPML (Geisser and Eddy, 1979) and WAIC (Watanabe, 2010) scores of the Bayesian Markov renewal mixture models

Usage

model.selection.scores(object)

Value

a list consisting of LPML and WAIC scores for gamma mixture models.

Arguments

object

An object of class BMRMM.

Details

The two scores can be used to compare different choices of isi_num_comp, i.e., the number of the mixture gamma components. Larger values of LPML and smaller values of WAIC indicate better model fits.
