We compute P-values, based on the Wilcoxon test with ties, to compare two conditions with array comparative genomic hybridization data, and we provide a simple interface to export and plot these P-values.

We compared catches of settlement-stage reef fishes in light traps attached to underwater speakers playing reef sounds with those of silent traps during a summer recruitment season at Lizard Island, Great Barrier Reef, Australia. Of the total 40191 reef fishes we collected, significantly more (67%; Wilcoxon and Binomial tests: p< 0.001) appeared in the traps with broadcast reef noise. Traps dep...

Methods All HIV1-positive patients of the participating clinic wards, aged over 13 and giving informed consent are included in the cohort. Patients receiving a first prescription of NVP between 1997 and 2008 are described at baseline and during follow-up according to their treatment status, ART-naïve or not. Chi-square test, signed rank Wilcoxon test, Mc Nemar test and log-rank test are used fo...

Context: Virtual machines provide isolation of services at the cost of hypervisors and more resource usage. This spurred the growth of systems like Docker that enable single hosts to isolate several applications, similar to VMs, within a low-overhead abstraction called containers. Motivation: Although containers tout low overhead performance, do they still have low energy consumption? Methodolo...

Methods Our aim was to evaluate the incidence of NOMI, to analyze results of treatment and to identify variables associated with mortality. Hospital records and clinical data of patients treated for NOMI during the last 12 years were reviewed. Clinical outcomes and factors influencing mortality were studied. Statistical analysis was performed to determine the significance of risk factors on mor...

Methods Study participants were GVK EMRI EMT instructors who attended the inaugural EMT refresher training course. These participants were from nine states within India and represented mixed educational backgrounds, including doctors and EMTs. After receiving a confidential unique ID, each study participant took a 30 multiple-choice question (MCQ) pre-test and a 60 MCQ post-test before and afte...

The well-known Mann–Whitney–Wilcoxon (MWW) statistic is based on empirical distribution estimates. However, the data are often drawn from smooth populations. Therefore, smoothness characteristic not preserved. In addition, several authors have pointed out that an inadmissible estimate. Thus, in this work, we develop versions of MWW function This approach preserves characteristics and allows eff...

where sgn(x) stands for the sign of x. We first present and prove two useful lemmas about the unpenalized weighted Wilcoxon estimator under possible local contamination. These results will be useful later to establish the asymptotic properties of the penalized Wilcoxon estimator. In the proof of the two lemmas, we frequently refer to the book of Hettmansperger and McKean (1998), abbreviated as ...
