coef.abclass {abclass}

Coefficient Estimates of A Trained Angle-Based Classifier

Description

Extract coefficient estimates from an abclass object.

Usage

## S3 method for class 'abclass'
coef(object, selection = c("cv_1se", "cv_min", "all"), ...)

Arguments

object

An object of class abclass.

selection

An integer vector for the indices of solution path or a character value specifying how to select a particular set of coefficient estimates from the entire solution path. If the specified abclass object contains the cross-validation results, one may set selection to "cv_min" (or "cv_1se") for the estimates giving the smallest cross-validation error (or the set of estimates resulted from the largest lambda within one standard error of the smallest cross-validation error). The entire solution path will be returned in an array if selection = "all" or no cross-validation results are available in the specified abclass object.

...

Other arguments not used now.

Value

A matrix representing the coefficient estimates or an array representing all the selected solutions.
