Le tau et le tau-b de Kendall pour la corrélation de variables ordinales simples ou catégorielles [PDF]

open access: yesTutorials in Quantitative Methods for Psychology, 2009
Dans le langage de tous les jours, l’expression « corrélation entre deux variables » est entendue et bien comprise de manière générale : c’est un lien, un rapport de correspondance grâce auquel la variation d’un attribut peut être associée à la variation

Multiple Ordinal Correlation Based on Kendall’s Tau Measure: A Proposal

open access: yesMathematics, 2021
The joint analysis of various ordinal variables is necessary in many experimental studies within research fields such as sociology and psychology. Therefore, the necessary measures of multiple ordinal dependence must be easy to interpret and facilitate ...

AXIOMATIC DETERMINATION OF A CLASS OF ORDINAL VARIATION MEASURES

open access: yesStudies in Logic, Grammar and Rhetoric, 2017
The article deals with the problem of the dispersion of ordinal variables. At first, it specifies the very concept of dispersion for this type of scale. Then some of the most known measures that fit to the concept of ordinal variation are recalled.

Bayesian test of independence and conditional independence of two ordinal variables [PDF]

open access: yesJournal of Statistical Theory and Applications (JSTA), 2015
For analysis of contingency tables with large sample size, classical approaches using approximate methods have high power. However, when the sample size is small or some cells have frequencies less than 5, classical approaches are so conservative.

Measuring risk with ordinal variables [PDF]

open access: yesThe Journal of Operational Risk, 2013
In this paper we propose a novel approach for measuring risks when the data available is expressed on an ordinal scale. As a result we obtain a new index of riskboundedbetween 0and 1,whichleadstoariskorderingthatisconsistentwith a stochastic dominance approach. The proposed measure, being nonparametric, can be applied to a wide range of problems, where

Regression with Ordered Predictors via Ordinal Smoothing Splines

open access: yesFrontiers in Applied Mathematics and Statistics, 2017
Many applied studies collect one or more ordered categorical predictors, which do not fit neatly within classic regression frameworks. In most cases, ordinal predictors are treated as either nominal (unordered) variables or metric (continuous) variables ...

Adaptive Sparse Clustering of Mixed Data Using Azzalini-Encoded Ordinal Variables

open access: yesAxioms
In this paper, we propose a novel sparse clustering method designed for high-dimensional mixed-type data, integrating Azzalini’s score-based encoding for ordinal variables. Our approach aims to retain the inherent nature of each variable type—continuous,

Comparison of Ordinal Response Modeling Methods like Decision Trees, Ordinal Forest and L1 Penalized Continuation Ratio Regression in High Dimensional Data

open access: yesIranian South Medical Journal, 2021
Background: Response variables in most medical and health-related research have an ordinal nature. Conventional modeling methods assume predictor variables to be independent, and consider a large number of samples (n) compared to the number of covariates
