MORE INFORMATIVE TESTING FOR BIVARIATE SYMMETRY
Authors:JCW RAYNER  O THAS
Institution:The University of Wollongong and Ghent University
Abstract:In testing for bivariate symmetry against arbitrary alternatives the well‐known test developed by Bowker in 1948 is shown to be a score test, and to have useful components. These components are asymptotically independent and asymptotically have the standard normal distribution. Moreover they assess particular pairs of cells for symmetry. These components can also be used in a data analytic manner to complement a test for bivariate symmetry against ordered alternatives.
Keywords:arbitrary and ordered alternatives  Bowker's test  components  score test
