A Weighted Rank-Sum Procedure for Comparing Samples with Multiple Endpoints.
For comparing the distribution of two samples with multiple endpoints, O'Brien (1984) proposed rank-sum-type test statistics. Huang et al. (2005) extended these statistics to the general nonparametric Behrens-Fisher hypothesis problem and obtained improved test statistics by replacing the ad hoc variance with the asymptotic variance of the rank-sum statistics. In this paper we generalize the wo...
متن کاملProcedures for comparing samples with multiple endpoints.
Five procedures are considered for the comparison of two or more multivariate samples. These procedures include a newly proposed nonparametric rank-sum test and a generalized least squares test. Also considered are the following tests: ordinary least squares, Hotelling's T2, and a Bonferroni per-experiment error-rate approach. Applications are envisaged in which each variable represents a quali...
متن کاملA group sequential Holm procedure with multiple primary endpoints.
We propose a group sequential Holm procedure when there are multiple primary endpoints. This method addresses multiplicities arising from multiple primary endpoints and from multiple analyses in a group sequential design. It has been shown to be a closed testing procedure and preserves the familywise error rate in the strong sense. When multiple endpoints are the only concern without an interim...
متن کاملWeighted Sum Formula for Multiple Zeta Values
Abstract. The sum formula is a basic identity of multiple zeta values that expresses a Riemann zeta value as a homogeneous sum of multiple zeta values of a given dimension. This formula was already known to Euler in the dimension two case, conjectured in the early 1990s for higher dimensions and then proved by Granville and Zagier independently. Recently a weighted form of Euler’s formula was o...
متن کاملComparing Two Treatments with Multiple Competing Risks Endpoints
The problem of testing for differences between two treatments with respect to multiple competing risk time-to-event endpoints is considered. Using a nonparametric approach, a multivariate two-sample statistic is proposed for simultaneous testing for differences in cumulative incidence of the multiple competing survival endpoints. Establishment of the statistical properties of the test requires ...
