| Abstract: | The logrank test procedure for testing bivariate symmetry against asymmetry in matched-pair data is proposed. The presented test statistic is based on Mantel-Haenszel type statistics evaluated at diagonal grid points on the plane obtained from distinct uncensored failure times. The asymptotic results of the proposed test are derived and an example is shown to illustrate the methodology. |
