Restricted Tweedie stochastic block models

open access: yesCanadian Journal of Statistics, EarlyView.
Abstract The stochastic block model (SBM) is a widely used framework for community detection in networks, where the network structure is typically represented by an adjacency matrix. However, conventional SBMs are not directly applicable to an adjacency matrix that consists of nonnegative zero‐inflated continuous edge weights.

A typology of models used in actuarial science

open access: hybridSouth African Actuarial Journal, 2006
This paper proposes a categorisation of the models used in actuarial science. It illustrates the application of that categorisation by using it to classify numerous such models. It is suggested that this categorisation, together with the illustrative classification, may be used as a typology for the classification of other such models, and that this ...

Subuniformity of harmonic mean p$$ p $$‐values

open access: yesCanadian Journal of Statistics, EarlyView.
Abstract We obtain several inequalities on the generalized means of dependent p$$ p $$‐values. In particular, the weighted harmonic mean of p$$ p $$‐values is strictly subuniform under several dependence assumptions of p$$ p $$‐values, including independence, negative upper orthant dependence, the class of extremal mixture copulas, and some Clayton ...

The Relevance of an Existential Conception of Nature [PDF]

open access: yes, 2014
It is often assumed that science provides the most accurate knowledge about nature. This view not only collapses distinctions between different forms of knowing but also results in a paradox whereby understanding what it means to exist in the world is ...

A probabilistic diagnostic for Laplace approximations: Introduction and experimentation

open access: yesCanadian Journal of Statistics, EarlyView.
Abstract Many models require integrals of high‐dimensional functions: for instance, to obtain marginal likelihoods. Such integrals may be intractable, or too expensive to compute numerically. Instead, we can use the Laplace approximation (LA). The LA is exact if the function is proportional to a normal density; its effectiveness therefore depends on ...

COVID-19 and Excess Mortality: An Actuarial Study

open access: yesRisks
The study of mortality is an ever-active field of research, and new methods or combinations of methods are constantly being developed. In the actuarial domain, the study of phenomena disrupting mortality and leading to excess mortality, as in the case of

AI and the Future of Disputing: Naming, Blaming, Claiming, and Preventing

open access: yesConflict Resolution Quarterly, EarlyView.
ABSTRACT This paper explores the transformative impact of artificial intelligence (AI) on dispute resolution mechanisms. Our analysis builds on the longstanding framework for explaining the stages through which disputes evolve: the “naming, blaming, claiming” model by Felstiner, Abel, and Sarat (1981).

Interconnected pathways and emerging therapies in chronic kidney disease and heart failure: A comprehensive review

open access: yesESC Heart Failure, EarlyView.
Abstract Chronic kidney disease (CKD) and chronic heart failure (HF) frequently coexist and, when comorbid, are associated with poorer outcomes. These two diseases have common risk factors, such as diabetes, obesity and hypertension, and common pathophysiological connected mechanisms, including inflammation, endothelial dysfunction, neurohormonal ...
