R Documentation

Selection of the number of iterations for iterative bias reduction smoothers

Description

The function cvobs gives the index of observations in each test set. This function is not intended to be used directly.

Usage

cvobs(n,ntest,ntrain,Kfold,type=
c("random", "timeseries", "consecutive", "interleaved"), npermut, seed)

Arguments

`n`	The total number of observations.
`ntest`	The number of observations in test set.
`ntrain`	The number of observations in training set.
`Kfold`	Either the number of folds or a boolean or `NULL`.
`type`	A character string in `random`,`timeseries`,`consecutive`, `interleaved` and give the type of segments.
`npermut`	The number of random draw (with replacement), used for `type="random"`.
`seed`	Controls the seed of random generator (via `set.seed`).

Value

Returns a list with in each component the index of observations to be used as a test set.
