Glossary of "Cladistics (2nd ed.)" by Kitching et al. (1998)

  • A statistical procedure for achieving a better estimate of the parametric variance of a distribution from small samples than the observed sample variance by averaging pseudoreplicate variances. The original data set is sampled without replacement to produce a pseudoreplicate that is smaller than the original. In first-order jackknifing, only a single original observation is excluded; in higher-order jackknifing, more than one original observation is excluded. See also bootstrap.
