A consistent test of independence based on a sign covariance related to Kendall's tau

, 2014
The most popular ways to test for independence of two ordinal random variables are by means of Kendall's tau and Spearman's rho. However, such tests are not consistent, only having power for alternatives with `monotonic' association.

Spatio‐Temporal Analysis of Human Thermal Comfort and Relationships With Large‐Scale Climate Indices Along Ghana's Coastal‐Urban Corridor From 1980 to 2020

International Journal of Climatology, EarlyView.
Four decades of UTCI data show increasing thermal stress along Ghana's coastal‐urban corridor, with very strong heat‐stress days rising by about 1.4 days/year. Random Forest–SHAP analysis with temporal validation identified AOD as the strongest model‐based predictor of monthly UTCI variability, followed by TSA, WHWP, and AMO.

Correlation Test Application of Supplier’s Ranking Using TOPSIS and AHP-TOPSIS Method

Cauchy: Jurnal Matematika Murni dan Aplikasi, 2016
The supplier selection process can be done using multi-criteria decision making (MCDM) methods in firms. There are many MCDM Methods, but firms must choose the method suitable with the firm condition.

Concordance of Preoperative Transvaginal Ultrasound and Intraoperative Findings in Fibroid Ablation Using Transcervical Ultrasound

Journal of Ultrasound in Medicine, EarlyView.
Objective To evaluate concordance between the number of uterine fibroids deemed clinically significant on preoperative transvaginal sonography (TVS) and the number of fibroids treated intraoperatively during transcervical radiofrequency ablation (RFA) under intrauterine ultrasound guidance.

szKendall: spatial-structural-zero-aware dissimilarity measures for subtype discovery using single cell Hi-C data

Nature Communications
High-throughput single-cell Hi-C technologies offer a powerful lens on cell-to-cell variability in the three-dimensional organization of the genome, yet their interpretation is constrained by extreme and uneven data sparsity.

On Concordance Measures for Discrete Data and Dependence Properties of Poisson Model

Journal of Probability and Statistics, 2009
We study Kendall's tau and Spearman's rho concordance measures for discrete variables. We mainly provide their best bounds using positive dependence properties. These bounds are difficult to write down explicitly in general.

Weight‐bearing computed tomography reveals greater anterior tibial translation and femorotibial rotation than magnetic resonance imaging in chronic anterior cruciate ligament deficiency: A prospective observational study

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose To compare anterior tibial translation and femorotibial rotation measurements obtained from conventional supine, non‐weight‐bearing magnetic resonance imaging (MRI) and weight‐bearing computed tomography (WBCT) in patients with chronic anterior cruciate ligament (ACL) tears. Methods WBCT of the knee acquired in full extension and at 30°

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.

Limited correlation between clinical failure and MRI graft status in the setting of revision anterior cruciate ligament reconstruction

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose To investigate whether clinically failed anterior cruciate ligament (ACL) reconstructions can be accurately identified using magnetic resonance imaging (MRI). Methods This prospective case series included 81 patients (mean age 33.5 ± 11.9 years, 50.6% male) with clinically failed ACL reconstructions defined by Lachman ≥ Grade 2, Pivot ...

Unveiling the Interplanetary Solar Radio Bursts of the 2024 Mother’s Day Solar Storm

The Astrophysical Journal Letters
We report on a comprehensive study of interplanetary type III radio bursts linked to X-class solar flares from NOAA active region 13664, which instigated the intense 2024 Mother’s Day solar storm, marked by a geomagnetic storm of −412 nT, the strongest ...
