Matrix-Tilted Archimedean Copulas [PDF]
Risks, 2021 The new class of matrix-tilted Archimedean copulas is introduced. It combines properties of Archimedean and elliptical copulas by introducing a tilting matrix in the stochastic representation of Archimedean copulas, similar to the Cholesky factor for ...

A New Family of Archimedean Copulas: The Half-Logistic Family of Copulas
Mathematics, 2023 In this research, we introduce a truncation of the half-logistic distribution function as a multiplicative Archimedean generator. The corresponding Archimedean copula is obtained, namely the half-logistic family.

On Construction of Bernstein-BĂ©zier Type Bivariate Archimedean Copula
Revstat Statistical Journal, 2022 In this paper, a new class of bivariate multi-parameter Archimedean copula based on Kendall distribution using Bernstein-BĂ©zier polynomials is introduced. The new class copula has flexible dependence properties depending on the polynomial degree and the

Quantile Regression Based on the Weighted Approach with Dependent Truncated Data
Mathematics, 2023 This paper discusses the estimation of parameters in the quantile regression model for dependent truncated data. To account for the dependence between the survival time and the truncated time, the Archimedean copula model is used to construct the ...
