Finding universal relations using statistical data analysis [PDF]

open access: yesPhysical Review D, 2023
We present applications of statistical data analysis methods from both bi- and multivariate statistics to find suitable sets of neutron star features that can be leveraged for accurate and EoS independent -- or universal -- relations.

Computation of tolerance ellipses for bivariate and trivariate normal populations

open access: yesJournal of Statistical Computation and Simulation, 2022
We consider the computation of the critical constants c of a p-content -confidence tolerance ellipse for bivariate and trivariate normal populations which are probably the most used multivariate normal distributions in applications.

A novel bivariate Lomax-G family of distributions: Properties, inference, and applications to environmental, medical, and computer science data

open access: yesAIMS Mathematics, 2023
This paper presents a novel family of bivariate continuous Lomax generators known as the BFGMLG family, which is constructed using univariate Lomax generator (LG) families and the Farlie Gumbel Morgenstern (FGM) copula. We have derived several structural
