title: Exact one-tailed 100p% upper limits for future sample repeatability relative standard deviations obtained in single- and multilaboratory repeatability studies.
abstract: Formulas are derived to obtain exact one-tailed 100p% upper limits (kappa(p) and nu(p)) for future sample repeatability relative standard deviations, based on a noncentral t-distribution, for multi- and single-laboratory repeatability studies, respectively, used in the validation of analytical methods.
