An overview of the goodness-of-fit test problem for copulas

open access: yes, 2012
We review the main "omnibus procedures" for goodness-of-fit testing for copulas: tests based on the empirical copula process, on probability integral transformations, on Kendall's dependence function, etc, and some corresponding reductions of dimension ...

Sustainability Orientation and Sustainable Innovation: Can Organisational Resilience Clarify the Missing Link?

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Although firms that integrate a sustainability orientation (SO) may experience a significant improvement in their resource efficiency, many, particularly small‐ and medium‐sized enterprises (SMEs), still struggle with the complexities of incorporating sustainability into their business models.

New results on perturbation-based copulas

open access: yesDependence Modeling, 2021
A prominent example of a perturbation of the bivariate product copula (which characterizes stochastic independence) is the parametric family of Eyraud-Farlie-Gumbel-Morgenstern copulas which allows small dependencies to be modeled.

Sound Financial Practices and Entrepreneurs' Socio‐Environmental Commitment: Revealing the Role of Financial Barriers

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Small enterprises (SEs) constitute a major component of economic systems, and their socio‐environmental commitment is critical for promoting societal well‐being. This paper examines the direct effect of sound financial practices on socio‐environmental commitment and evaluates the mediating role of financial constraints—specifically debt and ...

New copulas based on general partitions-of-unity and their applications to risk management (part II)

open access: yesDependence Modeling, 2017
We present a constructive and self-contained approach to data driven infinite partition-of-unity copulas that were recently introduced in the literature.

A Collection of New Trigonometric- and Hyperbolic-FGM-Type Copulas

open access: yesAppliedMath, 2023
Copula analysis was created to explain the dependence of two or more quantitative variables. Due to the need for in-depth data analysis involving complex variable relationships, there is always a need for new copula models with original features.

The Role of Institutional Pressures in Technology Adoption for Low‐Carbon Manufacturing

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Existing research highlights that the adoption of low‐carbon technologies in manufacturing operations is shaped by the external environment. However, limited understanding exists regarding how technology‐related uncertainty interacts with institutional pressures to influence firms' adoption strategies.

Orchestrating Ecosystem Resources for Sustainability: Coopetition, Digital Transformation, and Disruptive Sustainable Innovation

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT As sustainability transitions accelerate, firms increasingly engage in innovation ecosystems to pursue disruptive sustainable innovation (DSI). Nevertheless, empirical understanding regarding how innovation ecosystem coopetition—simultaneous cooperation and competition among interdependent actors—translates into sustainability‐oriented ...

Data‐driven simulation of crude distillation using Aspen HYSYS and comparative machine learning models

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Integrated Aspen HYSYS–machine learning framework for predicting product yields and quality variables. Abstract Crude oil refining is a complex process requiring precise modelling to optimize yield, quality, and efficiency. This study integrates Aspen HYSYS® simulations with machine learning techniques to develop predictive models for key refinery ...

Adaptive Bernstein Copulas and Risk Management

open access: yesMathematics, 2020
We present a constructive approach to Bernstein copulas with an admissible discrete skeleton in arbitrary dimensions when the underlying marginal grid sizes are smaller than the number of observations.
