A generalised hypergeometric distribution with its versatile shape of tails is introduced as a prior, and beta special cases are examined. A simulation study is carried out to investigate the sensitivity of four special cases of this beta prior family in terms of bias, frequentist coverage and mean square error and to determine their effect on robustness. Prediction bounds are derived for the lifetime of unused components using this beta prior family. A data set is used to illustrate and support some of the findings.enSouth African Statistical AssociationBayesian estimationBayesian prediction boundsFrequentist coverageGeneralised hypergeometric distributionH-FunctionMetropolis-Hastings algorithmRayleigh modelSquared error loss functionType II censored dataArticle
