Tests Based on Skewness and Kurtosis for Multivariate Normality
Communications for Statistical Applications and Methods, 2015 A measure of skewness and kurtosis is proposed to test multivariate normality. It is based on an empirical standardization using the scaled residuals of the observations. First, we consider the statistics that take the skewness or the kurtosis for each coordinate of the scaled residuals.

Properties and Applications of some Distributions derived from Frullani's integral [PDF]
, 2014 Frullani's integral dates from 1821, but a probabilistic interpretation of it has never been made. In this paper, Frullani's integral formula is shown to result from mixing a lifetime distribution by allowing the logarithm of the scale factor to be ...

Single‐Cell Transcriptomics and Deep Learning Link N‐(2‐Furoyl) Glycine to GLRX3 in Gastric Cancer
Med Research, EarlyView.ABSTRACT Gastric cancer remains a health burden, and its metabolic drivers are poorly defined. N‐(2‐furoyl) glycine, a circulating metabolite, has been implicated in tumor biology. We investigated its causal role in gastric cancer and the underlying mechanism.

Multivariate Kurtosis as a Tool for Comparing Copula Models
International Journal of Statistics and Probability, 2016 This paper studies the effectiveness of the Multivariate Kurtosis in comparing the Clayton Copula and the Farleigh-Gumbel-Morgenstern Copula in modeling when the actual populations follow either the bivariate exponential distribution or the bivariate normal distribution.

PLANTS, PEOPLE, PLANET, EarlyView.Our study tests how soil and plant biodiversity can enhance sustainability of crop production in Kenya. We tested whether mixtures of maize varieties performed better than monocultures and tested their response to arbuscular mycorrhizal fungi. Mycorrhizal responsiveness differed significantly by maize variety, and genetic mixtures outperformed ...
