In mclust: Gaussian Mixture Modelling for Model-Based Clustering, Classification, and Density Estimation

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").
