predict.sda: Shrinkage Discriminant Analysis 3: Prediction Step
Description
predict.sda performs class prediction.
Usage
# S3 method for sda
predict(object, Xtest, verbose=TRUE, ...)
Value
predict.sda predicts class probabilities for each test sample and returns
a list with two components:
- class
a factor with the most probable class assignment for each test sample, and
- posterior
a matrix containing the respective class posterior probabilities.
Arguments
- object
An sda fit object obtained from the function sda.
- Xtest
A matrix containing the test data set. Note that
the rows correspond to observations and the columns
to variables.
- verbose
Report shrinkage intensities (sda) and number of used features (predict.sda).
- ...
Additional arguments for generic predict.
