kfoldcv: Subsamples for k-fold Cross-Validation

Description

Computes feasible sample sizes for the k groups in k-fold cv if N/k is not an integer.

Usage

kfoldcv(k, N, nlevel=NULL)

Value

A vector of length k.

Arguments

k

number of groups.

N

total sample size.

nlevel

a vector of sample sizes for stratified sampling.

Details

If N/k is not an integer, k-fold cv is not unique. Determine meaningful sample sizes.

Examples

# 10-fold CV with N = 91

kfoldcv(10, 91)	

# \testonly{
k <- sample(5:15, 1)
k
N <- sample(50:150, 1)
N
stopifnot(sum(kfoldcv(k, N)) == N)
# }
