Example diagram of the definition of φ in the text. Here, ﹩\chi ^{2}﹩ represents the actual ﹩\chi ^{2}﹩, while φ is designed such that it exceeds ﹩\chi ^{2}﹩ except at the single point W. By minimizing φ we can find a point ﹩W^{*}﹩ that we know to have an equal or better ﹩\chi ^{2}﹩ than that at W.
