Wiley StatsRef: Statistics Reference Online - Signed‐rank Statistics
Wiley StatsRef: Statistics Reference Online, 2014Co-Authors: R. F. WoolsonAbstract:In a single sample, or with differences between paired observations in a matched-pair study, the observations may be ranked in order of their absolute values. The sign of the rank is then restored, and an appropriate statistic is calculated from the signed ranks. The most usual example is the Wilcoxon Signed-Rank Test. Keywords: nonparametric; distribution-free; rank; Wilcoxon; tied ranks

Wilcoxon Signed-Rank Test
Wiley Encyclopedia of Clinical Trials, 2008Co-Authors: R. F. WoolsonAbstract:This is a nonparametric Test procedure for the analysis of matched-pair data, based on differences, or for a single sample. The null hypothesis is that the differences, or individual observations in the single-sample case, have a distribution centered about zero. The absolute values are ranked. The Test statistic is the sum of the ranks for either the positive or the negative values. Examples and details, including large-sample properties, are given. Keywords: nonparametric; distribution-free; ranks; absolute differences; large samples; ARE; censored

Wilcoxon-signed rank Test for associated sequences
Statistics & Probability Letters, 2005Co-Authors: Isha Dewan, B. L. S. Prakasa RaoAbstract:Let X1,...,Xn be stationary associated random variables with one dimensional marginal distribution function F. We study the properties of the classical sign statistic and the Wilcoxon-signed rank statistic for Testing for shift in location in the above set up. In the process, we extend the Newman's inequality to functions of bounded variation which are mixtures of absolutely continuous component and discrete component only.

Improving the Wilcoxon signed rank Test by a kernel smooth probability integral transformation
Statistics & Probability Letters, 1Co-Authors: Dimitrios Bagkavos, Prakash PatilAbstract:Abstract This note extends the applicability of the Wilcoxon signed rank Test to data from asymmetric densities. The operational characteristics and asymptotic properties of the process are discussed in detail. Additionally, a real data example highlights the benefits gained in practice.
