Compute sample sizes for \(k\)-fold cross-validation.
Usage
kfcv(k, N)
Arguments
k
number of groups.
N
total sample size.
Value
A vector of length k containing \(k\) sample sizes.
Details
If N/k is an integer, the sample sizes are k `N/k's (N/k, N/k, ...),
otherwise the remainder will be allocated to each group as `uniformly' as
possible, and at last these sample sizes will be permuted randomly.
