Spearman’s rho modification in digital image processing

IOP Conference Series: Materials Science and Engineering, 2019
Abstract The article presents an alternative Spearman’s rank correlation pattern as an innovative method in detecting the edges of an image by defining characteristic points of the image. Edge detection methods can be counted as the image processing stage following the implementation of the “initial” image processing, which includes: use

Hyperbolic and Trigonometric Generators of Archimedean Copulas: Characteristics and Performance [PDF]

Sahand Communications in Mathematical Analysis
In 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.

On the exact region determined by Spearman’s rho and Spearman’s footrule

Journal of Computational and Applied Mathematics
We determine the lower bound for possible values of Spearman's rho of a bivariate copula given that the value of its Spearman's footrule is known and show that this bound is always attained. We also give an estimate for the exact upper bound and prove that the estimate is attained for some but not all values of Spearman's footrule.

Network divergence analysis identifies adaptive gene modules and two orthogonal vulnerability axes in pancreatic cancer

Molecular Oncology, EarlyView.
Tumors contain diverse cellular states whose behavior is shaped by context‐dependent gene coordination. By comparing gene–gene relationships across biological contexts, we identify adaptive transcriptional modules that reorganize into distinct vulnerability axes.

A fluctuation test for constant Spearman’s rho with nuisance-free limit distribution [PDF]

Computational Statistics & Data Analysis, 2014
A CUSUM type test for constant correlation that goes beyond a previously suggested correlation constancy test by considering Spearman's rho in arbitrary dimensions is proposed. Since the new test does not require the existence of any moments, the applicability on usually heavy-tailed financial data is greatly improved.
