Flexible use of copula-type model for dose-finding in drug combination clinical trials. [PDF]
Biometrics, 2022 Abstract Identification of the maximum tolerated dose combination (MTDC) of cancer drugs is an important objective in phase I oncology trials. Numerous dose‐finding designs for drug combination have been proposed over the years. Copula‐type models exhibit distinctive advantages in this task over other models used in existing competitive designs.

On the Moments of the Aggregate Discounted Claims with Dependence Introduced by a FGM Copula [PDF]
, 2011 In this paper, we investigate the computation of the moments of the compound Poisson sums with discounted claims when introducing dependence between the interclaim time and the subsequent claim size. The dependence structure between the two random variables is defined by a Farlie-Gumbel-Morgenstern copula.

Bivariate Unit-Weibull Distribution: Properties and Inference
Mathematics, 2023 In this article, we introduce a novel bivariate probability distribution that is absolutely continuous. Considering the Farlie–Gumbel–Morgenstern (FGM) copula and the unit-Weibull distribution, we can obtain a bivariate unit-Weibull distribution.

Mathematical and Computational Applications, 2022 The generalized half-logistic distribution is ideal to fit the lifetime of some products, such as ball bearings and electrical insulation. In this paper, we aim to extend this scope by creating a motivated bivariate version.

Wind Energy, Volume 26, Issue 9, Page 900-922, September 2023., 2023 Abstract Accurate and reliable assessment of wind energy potential has important implication to the wind energy industry. Most previous studies on wind energy assessment focused solely on wind speed, whereas the dependence of wind energy on wind direction was much less considered and documented.

A Copula-based Maintenance Modeling for Parallel Systems with Non-self Announcing Failures and Dependent Components [PDF]
International Journal of Supply and Operations Management, 2019 Based on a copula function this paper addresses a maintenance scheduling problem for parallel systems whose components are dependent and their failures are detected only by inspections. To carry out preventive maintenance actions, the decision process is

Health Economics, Volume 32, Issue 6, Page 1305-1322, June 2023., 2023 Abstract We develop a flexible two‐equation copula model to address endogeneity of medical expenditures in a distribution regression for health. The expenditure margin uses the compound gamma distribution, a special case of the Tweedie family of distributions, to account for a spike at zero and a highly skewed continuous part.
