Abstract
The Belle collaboration operates a general-purpose detector at the KEKB asymmetric energy e+ e- collider, performing a wide range of measurements in beauty, charm, tau and 2-photon physics. In this paper, the treatment of statistical problems in past and present Belle measurements is reviewed. Some open questions, such as the preferred method for quoting rare decay results, and the statistical treatment of the new B0/B0bar --> pi+ pi- analysis, are discussed.
