Normality assessment, few paradigms and use cases
Romanian Journal of Laboratory Medicine, 2022 Background: The importance of applying the normality tests is underlined by the way of continuing the statistical protocol for numerical data within inferential statistics, respectively by the parametric or non-parametric tests that we will apply further

Practical guide to using Kendall’s τ in the context of forecasting critical transitions
Royal Society Open Science, 2022 Recent studies demonstrate that trends in indicators extracted from measured time series can indicate an approach of an impending transition. Kendall’s τ coefficient is often used to study the trend of statistics related to the critical slowing down ...

NON-PARAMETRIC STATISTICS [PDF]
, 1981 This chapter discusses non-parametric statistics. It discusses some additional uses of the χ 2 distribution. The chapter explains how to test the independence of two criteria of classification and how to test whether the population from which the sampling is done is normal.
