Implementing Markovian models for extendible Marshall–Olkin distributions

Dependence Modeling, 2022
We derive a novel stochastic representation of exchangeable Marshall–Olkin distributions based on their death-counting processes. We show that these processes are Markov.

Local Exchangeability [PDF]

, 2022
Exchangeability -- in which the distribution of an infinite sequence is invariant to reorderings of its elements -- implies the existence of a simple conditional independence structure that may be leveraged in the design of statistical models and ...

A Graphical Description of Partial Exchangeability

, 2020
Partial exchangeability is sufficient for the identification of some causal effects of interest. Here we review the use of common graphical tools and the sufficient component cause model in the context of partial exchangeability.

A link between Kendall’s τ, the length measure and the surface of bivariate copulas, and a consequence to copulas with self-similar support

Dependence Modeling, 2023
Working with shuffles, we establish a close link between Kendall’s τ\tau , the so-called length measure, and the surface area of bivariate copulas and derive some consequences.

Exchange-Repairs: Managing Inconsistency in Data Exchange [PDF]

Journal on Data Semantics, 2014
In a data exchange setting with target constraints, it is often the case that a given source instance has no solutions. In such cases, the semantics of target queries trivialize. The aim of this paper is to introduce and explore a new framework that gives meaningful semantics in such cases by using the notion of exchange-repairs.

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 ...
