  ## S3 method for class 'densityMclust'
predict(object, newdata, what = c("dens", "cdens"), logarithm = FALSE, ...)

Arguments

object

an object of class 'densityMclust' resulting from a call to densityMclust.

newdata

a vector, a data frame or matrix giving the data. If missing the density is computed for the input data obtained from the call to densityMclust.

what

a character string specifying what to retrieve: "dens" returns a vector of values for the mixture density, cdens returns a matrix of component densities for each mixture component (along the columns).

logarithm

A logical value indicating whether or not the logarithm of the density or component densities should be returned.

...

further arguments passed to or from other methods.

Value

Returns a vector or a matrix of densities evaluated at newdata depending on the argument what (see above).
