A method for the elicitation of copulas

4 open, 2023
In this paper, we introduce a method to construct copulas. The method is based on combining the partial derivatives of two copulas. We prove that the proposed method provides a copula.

Signaler-Receiver “Exchangeability” Promotes Information Exchange in Animal Communication [PDF]

Animal Behavior and Cognition
Signals that inform prospective receivers of potential contingencies associated with the signaler or its environment may be innate, or may rely upon repeated association between signal production and a context relevant to the receiver, or theory of mind,

The exchangeability of shape

BMC Research Notes, 2010
Background Landmark based geometric morphometrics (GM) allows the quantitative comparison of organismal shapes. When applied to systematics, it is able to score shape changes which often are undetectable by traditional morphological studies and even by ...

Decision-theoretic foundations for statistical causality

Journal of Causal Inference, 2021
We develop a mathematical and interpretative foundation for the enterprise of decision-theoretic (DT) statistical causality, which is a straightforward way of representing and addressing causal questions.

Dependence on Tail Copula

J
In real-world scenarios, we encounter non-exchangeable dependence structures. Our primary focus is on identifying and quantifying non-exchangeability in the tails of joint distributions.

Establishing an Apheresis Medicine Program in a Resource‐Constrained Setting: A 5‐Year Experience From Lagos, Nigeria

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Establishing a comprehensive apheresis medicine program in a resource‐constrained setting presents significant structural, financial, and logistical challenges. Despite the growing clinical importance of apheresis services globally, published experience from sub‐Saharan Africa remains sparse.
