Package: classreg.learning.classif
Compact discriminant analysis class
Description
A CompactClassificationDiscriminant
object is a
compact version of a discriminant analysis classifier. The compact version does not
include the data for training the classifier. Therefore, you cannot perform some tasks
with a compact classifier, such as cross validation. Use a compact classifier for making
predictions (classifications) of new data.
Construction
