an <code><a rd-options="" href="/link/AM_mcmc_output?package=AntMAN&version=1.1.0" data-mini-rdoc="AntMAN::AM_mcmc_output">AM_mcmc_output</a></code> object, produced by calling <code><a rd-options="" href="/link/AM_mcmc_fit?package=AntMAN&version=1.1.0" data-mini-rdoc="AntMAN::AM_mcmc_fit">AM_mcmc_fit</a></code>.

A list of variables to consider for plotting. This function only produces meaningful plots for variables that have fixed dimension across the draws. If not specified, plots pertaining to M and K will be produced.

title

visualise a matrix of plots describing the MCMC results. This function is built upon GGally's plotting function ggpairs GGallyAntMAN.

Fits finite Bayesian mixture models with a random number of components. The MCMC algorithm implemented is based on point processes as proposed by Argiento and De Iorio (2019) <arXiv:1904.09733> and offers a more computationally efficient alternative to reversible jump. Different mixture kernels can be specified: univariate Gaussian, multivariate Gaussian, univariate Poisson, and multivariate Bernoulli (latent class analysis). For the parameters characterising the mixture kernel, we specify conjugate priors, with possibly user specified hyper-parameters. We allow for different choices for the prior on the number of components: shifted Poisson, negative binomial, and point masses (i.e. mixtures with fixed number of components).
