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 than the observed sample variance by averaging pseudoreplicate variances. The original data set is sampled with replacement to produce a pseudoreplicate of the same dimensions as the original. See also jackknife.

Glossary of Plant Systematics (1st ed.) by Simpson (2006)

  • A method of evaluating cladogram robustness that reanalyzes the data of the original character × taxon matrix by selecting (resampling) characters at random, such that a given character can be selected more than once.
