nMclustParamsShared: Number of Parameters Shared Across Gaussian Mixture...

In radeksalac/mclustSBIC: Bayesian Information Criterion for Singular Gaussian Mixture Models

Description

Number of parameters shared across components of a given parameterized Gaussian mixture model, that is not counting the mixture parameters

Usage

  nMclustParamsShared <- function (modelName, d, noise = FALSE,
                                 ...)

Arguments

modelName	A character string indicating the model to be fitted in the EM phase of clustering. The help file for mclustModelNames describes the available models.
d	Number of variables in the data.
noise	A logical or numeric vector indicating an initial guess as to which observations are noise in the data. If numeric the entries should correspond to row indexes of the data. If supplied, a noise term will be added to the model in the estimation.
...	Catches unused arguments in indirect or list calls via do.call.

Value

Return an object of class 'numeric', which is the number of parameters shared across components excluding the mixture parameters.
