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

### Examples

    #------10-fold crossvalidation error using the LDA classifier---
    data(bupa)
    crossval(bupa,method="lda",repet=10)
    #------5-fold crossvalidation error using the knn classifier---
    data(colon)
    crossval(colon,nparts=5,method="knn",kvec=3,repet=5)
