Copula calibration

open access: yesElectronic Journal of Statistics, 2014
We propose notions of calibration for probabilistic forecasts of general multivariate quantities. Probabilistic copula calibration is a natural analogue of probabilistic calibration in the univariate setting. It can be assessed empirically by checking for the uniformity of the copula probability integral transform (CopPIT), which is invariant under ...

Data‐Driven Analysis of Green Logistics Strategies for the Logistics and Transportation Companies: A Bipolar Fuzzy Methodology

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Global imperatives, such as climate change, environmental concerns, and carbon emissions, make green transformation an inevitability in the logistics sector. Green logistics strategy formulation is an economic choice problem, but it also turns out to be a multicriteria decision‐making (MCDM) process that encompasses the triple bottom line (TBL)

From Demand Stability to Environmental Responsibility: How Ordered Backlogs Shape Firm Behaviour

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Ordered backlogs are the confirmed and yet to be delivered customer orders, which may have multiple advantages to firms. We investigate how ordered backlogs influence firms' future environmental misconduct. Drawing on organisational slack theory, we argue that ordered backlogs as a form of demand‐side slack can reduce environmental misconduct.

Transformations of copulas.

open access: yesKybernetika, 2005
Summary: Transformations of copulas by means of increasing bijections on the unit interval and attractors of copulas are discussed. The invariance of copulas under such transformations as well as the relationship to maximum attractors and Archimax copulas is investigated.

Internal Drivers of Circular Economy: The Role of Quality Management and Digitalization

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT The implementation by organizations of environmental practices related to circular economy can play a key role in helping solve important environmental problems such as climate change, pollution, and overconsumption of natural resources. A relevant theoretical and practical research topic is to study the role of internal determinants that can ...
