R: Density for Parameterized MVN Mixtures

dens {mclust}

R Documentation

Density for Parameterized MVN Mixtures

Description

Computes densities of observations in parameterized MVN mixtures.

Usage

dens(modelName, data, logarithm = FALSE, parameters, warn=NULL, ...)

Arguments

`modelName`	A character string indicating the model. The help file for `mclustModelNames` describes the available models.
`data`	A numeric vector, matrix, or data frame of observations. Categorical variables are not allowed. If a matrix or data frame, rows correspond to observations and columns correspond to variables.
`logarithm`	A logical value indicating whether or not the logarithm of the component densities should be returned. The default is to return the component densities, obtained from the log component densities by exponentiation.
`parameters`	The parameters of the model: `pro` The vector of mixing proportions for the components of the mixture. `mean` The mean for each component. If there is more than one component, this is a matrix whose kth column is the mean of the kth component of the mixture model. `variance` A list of variance parameters for the model. The components of this list depend on the model specification. See the help file for `mclustVariance` for details.
`warn`	A logical value indicating whether or not a warning should be issued when computations fail. The default is `warn=FALSE`.
`...`	Catches unused arguments in indirect or list calls via `do.call`.

Value

A numeric vector whose ith component is the density of the ith observation in data in the MVN mixture specified by parameters.
