Hyperbolic and Trigonometric Generators of Archimedean Copulas: Characteristics and Performance [PDF]
Sahand Communications in Mathematical AnalysisIn this paper, hyperbolic and trigonometric functions, based on cosecant and cotangent as generator function for the family of Archimedean copula, are proposed. For these families, the dependence characteristics are compared.

Kendall’s tau-type rank statistics in genome data
Applications of Mathematics, 2008 High-dimensional data models abound in genomics studies, where often inadequately small sample sizes create impasses for incorporation of standard statistical tools. Conventional assumptions of linearity of regression, homoscedasticity and (multi-) normality of errors may not be tenable in many such interdisciplinary setups.

The prevalence of cannabidiol (CBD) use in North America and Europe: A meta‐analysis
Addiction, EarlyView.Abstract Background and aims The global cannabidiol (CBD) market has expanded in recent years. Several studies suggest CBD use, whether for medical or recreational purposes, is on the rise; however, no systematic assessments of its prevalence have been conducted so far. This meta‐analysis aimed to estimate the prevalence of CBD use in North America and

Kendall’s tau and kendall’s partial correlation: two BASIC programs for microcomputers [PDF]
Behavior Research Methods, Instruments, & Computers, 1987 Nonparametric rank-ordercorrelationprocedures, such as Spearman's rho and Kendall's tau, are often used as alternativesto Pearson's r, their parametric counterpart, when assumptions underlying that procedure cannot be met. Kendall's tau is a particularly useful alternative in that it may be generalizedto a partial correlation coefficient.
