NMixCluster: Clustering based on the MCMC output of the mixture model

Description

TO BE ADDED.

This function only works for models with a fixed number of mixture components.

Usage

NMixCluster(object, ...)
# S3 method for default
NMixCluster(object, ...)
# S3 method for GLMM_MCMC
NMixCluster(object,
   prob = c("poster.comp.prob", "quant.comp.prob", "poster.comp.prob_b",
            "quant.comp.prob_b", "poster.comp.prob_u"),
   pquant = 0.5, HPD = FALSE, pHPD = 0.95, pthresh = -1, unclass.na = FALSE, ...)

Value

A data.frame with three (when HPD is FALSE) or five (when HPD is TRUE) columns.

Arguments

object

an object of apropriate class.

prob

character string which identifies estimates of the component probabilities to be used for clustering.

pquant

when prob is either “quant.comp.prob” or “quant.comp.prob_b”, argument pquant is the probability of the quantile of the component probabilities to be used for clustering.

HPD

logical value. If TRUE then only those subjects are classified for which the lower limit of the pHPD*100% HPD credible interval of the component probability exceeds the value of ptrash.

pHPD

credible level of the HPD credible interval, see argument HPD.

pthresh

an optional threshold for the estimated component probability (when HPD is FALSE) or for the lower limit of the HPD credible interval (when HPD is TRUE) to classify a subject. No effect when pthresh is negative.

unclass.na

logical value taken into account when pthresh is positive. If unclass.na is TRUE, unclassified subjects get classification NA. If unclass.na is FALSE, unclassified subjects create a separate (last) group.

...

optional additional arguments.
