When t-tests or Wilcoxon-Mann-Whitney tests won't do.
t-Tests are widely used by researchers to compare the average values of a numeric outcome between two groups. If there are doubts about the suitability of the data for the requirements of a t-test, most notably the distribution being non-normal, the Wilcoxon-Mann-Whitney test may be used instead. However, although often applied, both tests may be invalid when discrete and/or extremely skew data...
متن کاملGene set enrichment analysis using Wilcoxon tests
Gene set enrichment analysis (GSEA) is typically based on tests derived from the KolmogorovSmirnov, which is underpowered and a need for simpler methods has been identified.[2] The wgsea package contains functions for conducting GSEA using a Wilcoxon test to test for differences in the distribution of p values between SNPs within the gene set under test and a control set of SNPs. The mean of th...
متن کاملUnderstanding Regression versus Variance Tests for Social Interactions
This article is designed to understand the relationship between two approaches to the empirical analysis of social interactions. The first approach is the use of linear regressions to uncover social interactions. This approach estimates social interaction effects through changes in the conditional (linear) expectation of individual outcomes when group-level variables are included in the conditi...
متن کاملPermutation versus Bootstrap Significance Tests in Multiple Regression and Anova
Kempthorne's (1952) formulation of the randomization test is extended to yield a permutational analog of the bootstrap significance test. In the new test, residuals of a multiple regression are permuted instead of being bootstrapped. The test is an attractive alternative for Oja's test that permutes predictors (Austr. J.
متن کامل2-Banach stability results for the radical cubic functional equation related to quadratic mapping
The aim of this paper is to introduce and solve the generalized radical cubic functional equation related to quadratic functional equation$$fleft(sqrt[3]{ax^{3}+by^{3}}right)+fleft(sqrt[3]{ax^{3}-by^{3}}right)=2a^{2}f(x)+2b^{2}f(y),;; x,yinmathbb{R},$$for a mapping $f$ from $mathbb{R}$ into a vector space. We also investigate some stability and hyperstability results for...
