An extension of the Pitman–Koopman Theorem
Published online by Cambridge University Press: 24 October 2008
Abstract
The theorems of Pitman and Koopman on laws of chance that yield sufficient statistics are extended to laws where the parameter or the observable, or both, may admit only a discrete set of values. The method depends on making changes, not necessarily small, within the values permitted for the variables, but it is still necessary to assume a solubility condition.
