predict.sda {sparseLDA}R Documentation

Predict method for Sparse Discriminant Methods

Description

Prediction functions for link{sda} and link{smda}.

Usage

## 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

A list with components:

class The classification (a factor)
posterior posterior probabilities for the classes (or subclasses for link{smda})
x the scores
