Robust Bernoulli Mixture Models for Credit Portfolio Risk
ABSTRACT This paper presents comparison results and establishes risk bounds for credit portfolios within classes of Bernoulli mixture models, assuming conditionally independent defaults that are stochastically increasing in a common risk factor. We provide simple and interpretable conditions on conditional default probabilities that imply a comparison ...

Agreement Between the Harmonized and the Self-Explanatory Versions of the Revised ALS Functional Rating Scale in a Clinical Setting. [PDF]
ABSTRACT Introduction/Aims The harmonized version of the ALS Functional Rating Scale ‐ Revised (ALSFRS‐R) is typically administered according to standard operating procedures (SOPs) to ensure procedural consistency. In contrast, obtaining the self‐explanatory (SE) version of the ALSFRS‐R does not include the use of SOPs.

Systemic risk in the insurance sector: A semi‐parametric approach based on Spearman's rho
Abstract We propose a new method to measure systemic risk in the global insurance sector by analyzing interconnectedness among firms under different market conditions. Using a semi‐parametric approach that relies on the Spearman correlation and copula‐based partial dependence, we assess relationships in relatively stable, extremely bullish, and ...
