Placement Test for the Behrens-Fisher problem.
Description
Returns the test based on placements for the Behrens-Fisher problem. This test was developed by Fligner and Policello (1981); see, also, Section 2.11 of Hettmansperger and McKean (2011) and Section 4.4 of Hollander and Wolfe (1999). The version computed by fp.test is discussed in Section 3.4 of Kloke and McKean (2014)/Section 3.6 of Kloke and McKean (2024).
