How to compare small multivariate samples using nonparametric tests

In plant pathology, in particular, and plant science, in general, experiments are often conducted to determine disease and related responses of plants to various treatments. Typically, such data are multivariate, where different variables may be measured on different scales that can be quantitative, ordinal, or mixed. To analyze these data, we propose different nonparametric (rank-based) tests ...

Permutation Tests to Compare Survival Curves for Matched Data

Riassunto: L’obiettivo di questo lavoro è sviluppare un test per il confronto della sopravvivenza tra gruppi di soggetti appaiati in proporzione non fissa. L’appaiamento produce dati stratificati, con strati spesso di dimensione esigua e con forme di dipendenza entro strato difficili da identificare. Si è pertanto esplorato, in questo contesto, l’uso di test di permutazione quale possibile alte...

Error in statistical tests of error in statistical tests

BACKGROUND A recent paper found that terminal digits of statistical values in Nature deviated significantly from an equiprobable distribution, indicating errors or inconsistencies in rounding. This finding, as well as the discovery that a large percentage of p values were inconsistent with reported test statistics, led to a great deal of concern in the popular press and scientific community. Th...
