control.errorest {ipred}

Control Error Rate Estimators

Description

Some parameters that control the behaviour of errorest.

Usage

control.errorest(k = 10, nboot = 25, strat = FALSE, random = TRUE, 
                 predictions = FALSE, getmodels=FALSE, list.tindx = NULL)

Arguments

k

integer, specify $k$ for $k$-fold cross-validation.

nboot

integer, number of bootstrap replications.

strat

logical, if TRUE, cross-validation is performed using stratified sampling (for classification problems).

random

logical, if TRUE, cross-validation is performed using a random ordering of the data.

predictions

logical, indicates whether the prediction for each observation should be returned or not (classification and regression only). For a bootstrap based estimator a matrix of size 'number of observations' times nboot is returned with predicted values of the ith out-of-bootstrap sample in column i and 'NA's for those observations not included in the ith out-of-bootstrap sample.

getmodels

logical, indicates a list of all models should be returned. For cross-validation only.

list.tindx

list of numeric vectors, indicating which observations are included in each bootstrap or cross-validation sample, respectively.

Value

A list with the same components as arguments.
