When the null is composite, the situation is tricky because the test statistic does not have a definite distribution. WebIn practice, one may evaluate different choices of t ( s) to determine the empirically optimal one. For a composite hypothesis testing problem in (1), we define Θ 1 ⊆ R as a neighborhood of the true value of θ1. The corresponding notations for θ2, η 1 and η 2 are Θ 2 ⊆ R, H 1 ⊆ R w and H 2 ⊆ R w, respectively. in and out burger palm trees
