## S3 method for class 'sda'
predict(object, newdata = NULL, ...)
## S3 method for class 'smda'
predict(object, newdata = NULL, ...)

Arguments

object

an object of class link{sda} or link{smda}

newdata

a matrix or data frame of predictors

...

arguments passed to link[MASS]{predict.lda}

Details

The current implementation for mixture discriminant models current predicts the subclass probabilities.

Value

class

The classification (a factor)

posterior

posterior probabilities for the classes (or subclasses for link{smda})

x

the scores
