plotScatter (Package: bayesMCClust) :

Produces three scatter plots of MCMC draws of selected transition probabilities over all clusters/groups.

plotLikeliPaths (Package: bayesMCClust) :

Plots paths of all sorts of likelihood and (prior) densities, like the log-likelihood, log posterior density, log classification likelihood and the entropy all including markings for the position of the maximum value, and further log prior densities for η, β, ξ and e (depending on availability/model type).

MNLAuxMix (Package: bayesMCClust) :

This function provides Bayesian multinomial logit regression using auxiliary mixture sampling. See Fruehwirth-Schnatter and Fruehwirth (2010). That is an MCMC sampler that is also used for the mixtures-of-experts extension of Dirichlet Multinomial (dmClustExtended) and Markov chain clustering (mcClustExtended). It requires four mandatory arguments: Data, Prior, Initial and Mcmc; each representing a list of (mandatory) arguments: Data contains data information, Prior contains prior information, Initial contains information about starting conditions (initial values) and Mcmc contains the setup for the MCMC sampler.

mcClustering (Package: bayesMCClust) :

This function provides Markov chain clustering with or without multinomial logit model (mixtures-of-experts) extension (see References). That is an MCMC sampler for the mixtures-of-experts extension of Markov chain clustering. It requires four mandatory arguments: Data, Prior, Initial and Mcmc; each representing a list of (mandatory) arguments: Data contains data information, Prior contains prior information, Initial contains information about starting conditions (initial values) and Mcmc contains the setup for the MCMC sampler.

dmClustering (Package: bayesMCClust) :

This function provides Dirichlet Multinomial Clustering with or without multinomial logit model (mixtures-of-experts) extension (see References). That is an MCMC sampler for the mixtures-of-experts extension of Dirichlet Multinomial clustering. It requires four mandatory arguments: Data, Prior, Initial and Mcmc; each representing a list of (mandatory) arguments: Data contains data information, Prior contains prior information, Initial contains information about starting conditions (initial values) and Mcmc contains the setup for the MCMC sampler.

calcVariationDMC (Package: bayesMCClust) :

Calculates the posterior expectation of the variance of the individual transition probabilities as well as posterior expectation and standard deviation of the row-specific unobserved heterogeneity measure in each group to analyse how much unobserved heterogeneity is present in the various clusters (see Pamminger and Fruehwirth-Schnatter (2010) in References).
● Data Source: CranContrib
● Keywords: cluster
● Alias: calcVariationDMC

calcTransProbs (Package: bayesMCClust) :

Calculates the posterior expectation and standard deviations of the average cluster-specific transition matrices and also offers some other analyses like plotting paths of MCMC draws.
