logLik.MclustDA {mclust} | R Documentation

## Log-Likelihood of a `MclustDA` object

### Description

Returns the log-likelihood for a `MclustDA` object.

### Usage

      ## S3 method for class 'MclustDA'
    logLik(object, data, ...)

### Arguments

`object` | an object of class `'MclustDA'` resulting from a call to `MclustDA`.
`data` | the data for which the log-likelihood must be computed. If missing, the observed data from the `'MclustDA'` object is used.
`...` | further arguments passed to or from other methods.

### Value

Returns an object of class `'logLik'` with an element providing the maximized log-likelihood, and further arguments giving the number of (estimated) parameters in the model (`"df"`) and the sample size (`"nobs"`).
