This function calculates variance corrected for non-independence of k-fold iterations. See Appendix of Shcheglovitova & Anderson (2013) and other references (Miller 1974; Parr 1985; Shao and Wu 1989) for additional details.
A numeric vector.
Number of k-fold iterations.
This function calculates variance that is corrected for the non-independence of k cross-validation iterations. Following Shao and Wu (1989):
Sum Of Squares * ((n-1)/n)
where n = the number of k-fold iterations.
A numeric value of the corrected variance.
