A caveat on the use of a revised bootstrap algorithm
Psychometrika(1986)
摘要
A recently suggested revision of Efron's bootstrap algorithm for small bivariate samples discards bootstrap samples having
fewer than 3 distinct points in order to prevent degeneracies in Pearson'sr. Examples are given showing that this approach may severely underestimate the variance of sample moments when sample sizes
are very small.
