• The literature is old and rich, with a wide variety of statistics having being designed and analyzed, both for the unidimensional and the multivariate setting. (mdpi.com)
  • Using an entropic smoothing of the Wasserstein distance, we connect these to very different tests including multivariate methods involving energy statistics and kernel based maximum mean discrepancy and univariate methods like the Kolmogorov-Smirnov test, probability or quantile (PP/QQ) plots and receiver operating characteristic or ordinal dominance (ROC/ODC) curves.

  • It is nevertheless true that, whereas these methods have already proved highly effective in other applied areas of knowledge such as biostatistics or social sciences, nonparametric analyses in reliability currently form an interesting area of study that has not yet been fully explored.

  • The text begins with classical nonparametric hypotheses testing, including the sign, Wilcoxon sign-rank and rank-sum, Ansari-Bradley, Kolmogorov-Smirnov, Friedman rank, Kruskal-Wallis H, Spearman rank correlation coefficient, and Fisher exact tests. (routledge.com)
  • I need to choose a good dataset with at least two variables because I'll need to compare them by calculating measures of association, performing two-sample tests and maybe doing a nonparametric regression on R, ... Therefore, I was thinking about choosing a dataset about COVID 19 because. (talkstats.com)

  • In most nonparametric statistical tests, the original scores or observations are replaced by another variable containing less information. (uchicago.edu)
  • Nonparametric Tests 3.1 Introduction Nonparametric , or distribution free tests are so-called because the assumptions underlying their use are "fewer and weaker than those associated with parametric tests" (Siegel & Castellan, 1988, p. 34). (sputtr.com)
  • A novel presentation of rank and permutation tests, with accessible guidance to applications in R Nonparametric testing problems are frequently encountered in many scientific disciplines, such as engineering, medicine and the social sciences. (worldcat.org)
  • consider nonparametric lack-of-fit tests in presence of heteroscedastic variances. (k-state.edu)
  • We will also investigate correlation, regression, and one-way analysis of variance techniques in a nonparametric setting. (amherst.edu)
  • And because nonparametric statistical techniques are valid under less restrictive assumptions than those of a specified distribution type, they are very versatile, and they have found applications in many new methods of analysis. (iu.edu)

  • Our analysis suggests that the link between IT and increased productivity emerged well before the recent surge in the aggregate productivity statistics and that the current macroeconomic productivity revival may in part reflect the contributions of intangible capital accumulated in the past. (psu.edu)
  • The coefficient of variation is suggested by Francis and Kannenberg (1987) as a stability statistic through the combination of the coefficient of variation, mean yield, and environmental variance. (manzik.com)
