These conditions may be applied to obtain admissibility of (i) the best invariant procedure for estimating a two-dimensional location parameter and (ii) procedures which are Bayes in the class of procedures invariant under two-dimensional translation, the prior distribution being over values of some other parameter.admissibilitytwo-dimensional location parameterinvarianceestimation of the location parametermultiple decisionsBayes in the class of invariant proceduresStatistics and ProbabilityArticle
