Local Dependence for Bivariate Weibull Distributions Created by Archimedean Copula

open access: yesمجلة بغداد للعلوم, 2021
In multivariate survival analysis, estimating the multivariate distribution functions and then measuring the association between survival times are of great interest.

Non–Standard Analysis Revisited: An Easy Axiomatic Presentation Oriented Towards Numerical Applications

open access: yesInternational Journal of Applied Mathematics and Computer Science, 2022
Alpha-Theory was introduced in 1995 to provide a simplified version of Robinson’s non-standard analysis which overcomes the technicalities of symbolic logic.

Modelling Heavy Tailed Phenomena Using a LogNormal Distribution Having a Numerically Verifiable Infinite Variance

open access: yesMathematics, 2023
One-sided heavy tailed distributions have been used in many engineering applications, ranging from teletraffic modelling to financial engineering. In practice, the most interesting heavy tailed distributions are those having a finite mean and a diverging

Nonlinear distance measures under the framework of Pythagorean fuzzy sets with applications in problems of pattern recognition, medical diagnosis, and COVID-19 medicine selection

open access: yesBeni-Suef University Journal of Basic and Applied Sciences, 2023
Background The concept of Pythagorean fuzzy sets (PFSs) is an utmost valuable mathematical framework, which handles the ambiguity generally arising in decision-making problems.

Goal programming associated with the non-archimedean infinitesimal: a case study applied in the agricultural sector

open access: yesProduction, 2021
Paper aims This work presents a multi-objective method based on goal programming associated with non-Archimedean infinitesimal (NAI) (Improved Weighted Goal Programming method, input-oriented IWGP-MCDEA-BCC).

Permutation Tests Based on the Copula-Graphic Estimator and Their Use for Survival Tree Construction. [PDF]

open access: yesStat Med
ABSTRACT Survival trees are popular alternatives to Cox or Aalen regression models that offer both modeling flexibility and graphical interpretability. This paper introduces a new algorithm for survival trees that relaxes the assumption of independent censoring. To this end, we use the copula‐graphic estimator to estimate survival functions.

Non-local non-linear sigma models

open access: yesJournal of High Energy Physics, 2019
We study non-local non-linear sigma models in arbitrary dimension, focusing on the scale invariant limit in which the scalar fields naturally have scaling dimension zero, so that the free propagator is logarithmic.
