The Jackknife method is found to require relatively small sample size to attain consistency in its estimate while Bootstrap requires larges ample size. Bootstrap is also found to always underestimate the standard error of its estimates.enBootstrap, Coefficient of variation, Jackknife, Sample size, ParametricArticle
