Estimation of copula-based semiparametric time series models [PDF]
, 2005 This paper studies the estimation of a class of copula-based semiparametric stationary Markov models. These models are characterized by nonparametric invariant (or marginal) distributions and parametric copula functions that capture the temporal ...

A New Form of Farlie-Gumbel-Morgenstern Copula: A Comparative Simulation Study and Application
Journal of Statistical Theory and Applications (JSTA), 2021 In this study a new mixture copula has been obtained by creating a linear combination of product copula with copula which is obtained with marginal distributions of order statistics which was proposed by Dolati and Úbeda-Flores, Kybernetika.

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.
