Convergence of rank based degree-degree correlations in random directed networks [PDF]
, 2014 We introduce, and analyze, three measures for degree-degree dependencies, also called degree assortativity, in directed random graphs, based on Spearman's rho and Kendall's tau.

Graphing methods for Kendall's {\tau}
, 2023 Ranked data is commonly used in research across many fields of study including medicine, biology, psychology, and economics. One common statistic used for analyzing ranked data is Kendall's {\tau} coefficient, a non-parametric measure of rank correlation which describes the strength of the association between two monotonic continuous or ordinal ...

Nutrition in Clinical Practice, EarlyView.Abstract Background Diagnosing malnutrition in patients with pediatric cancer is challenging because tumor masses can interfere with anthropometric measurements. STRONGkids considers cancer a general risk factor, whereas Screening Tool for Childhood Cancer (SCAN) classifies patients as at risk or not, potentially missing those who need nutrition ...

Distilling food web dynamics: top–down and bottom–up drivers of extinction and trophic cascades
Oikos, EarlyView.Quantifying population dynamics is a fundamental challenge in ecology and evolutionary biology, particularly for species that are cryptic, microscopic, or extinct. Traditional approaches rely on continuous representations of population size, but in many cases, the precise number of individuals is unknowable.

Nested Archimedean Copulas Meet R: The nacopula Package [PDF]
The package nacopula provides procedures for constructing nested Archimedean copulas in any dimensions and with any kind of nesting structure, generating vectors of random variates from the constructed objects, computing function values and probabilities

Linking differences in personality to demography in the wandering albatross
Oikos, EarlyView.Population dynamics are shaped by individual differences. With a good understanding of the relationships between individual differences and vital rates, population models can be improved to yield more realistic and detailed demographic projections. Personality is expected to shape individual differences in performance.

On Kendall's Tau for Order Statistics
, 2018 Every copula $ C $ for a random vector $ {\bf X}=(X_1,\dots,X_d) $ with identically distributed coordinates determines a unique copula $ C_{:d} $ for its order statistic $ {\bf X}_{:d}=(X_{1:d},\dots,X_{d:d}) $. In the present paper we study the dependence structure of $ C_{:d} $ via Kendall's tau, denoted by $ $. As a general result, we show that $

Advancing Extracellular Vesicle Research: A Review of Systems Biology and Multiomics Perspectives
PROTEOMICS, EarlyView.ABSTRACT Extracellular vesicles (EVs) are membrane‐bound vesicles secreted by various cell types into the extracellular space and play a role in intercellular communication. Their molecular cargo varies depending on the cell of origin and its functional state.
