predictor-class: Class "predictor"

In cancerclass: Development and validation of diagnostic tests from high-dimensional molecular data

Description

An object of this class is returned by the function predict(...) and represents a nearest centroid predictor learned on a training data set.

Objects from the Class

Objects can be created by the call new("predictor", ...).

Slots

predictor:

Object of class "predictor"

cl:

Character string or number specifying one of the two classes.

method:

Character string specifying the feature selection method that was used for predictor construction: Possible values are "cor", "student.test", "welch.test", "wilcoxon.test", "foldchange", "copa", "os", "ort", "shift", "throw".

hparam:

Hyperparameter needed for some of the feature selection methods. For methods copa, ors and os: Quantile (e.g. 0.75, 0.9, 0.95) used in order to detect outliers. For methods shift and throw: the minimum number of samples in each class after applying shift or throw.

type:

Type of calculation. Loo (leave one out) or prediction (simple prediction).

fdata:
