Sample sizes for k-fold cross-validation
Compute sample sizes for k-fold cross-validation.
kfcv(k, N)
k |
number of groups. |
N |
total sample size. |
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.
A vector of length k containing k sample sizes.
