crossval {dprep}R Documentation

Cross validation estimation of the misclassification error

Description

Computation of the misclassification error for the LDA, KNN and rpart cllasifiers by cross validation

Usage

crossval(data, nparts = 10, method = c("lda", "knn", "rpart"), 
kvec = 5, repet)

Arguments

data The name of the dataset
nparts The number of folds in which the dataset is divided. By default nparts=10
method The name of the classifier to be used: LDA,KNN, Rpart
kvec The number of nearest neighbors to be used for the KNN classifier
repet The number of repetitions

Value

Returns the mean misclassification crossvalidation error of the classifier obtained on a given number of repetitions
