Modeling and Performance of Bonus-Malus Systems: Stationarity versus Age-Correction

Risks, 2014
In a bonus-malus system in car insurance, the bonus class of a customer is updated from one year to the next as a function of the current class and the number of claims in the year (assumed Poisson).

Applying the Rules of Evidence to Expert Testimony About Risk

Behavioral Sciences &the Law, EarlyView.
ABSTRACT Expert opinion about dangerousness or risk is common at sentencing, criminal commitment proceedings and some types of pretrial detention hearings. This article argues that such evidence must be (1) “material” (logically relevant, empirically generalizable, and epistemologically germane), (2) “probative” (a measure of accuracy, which is ...

Market valuation in the framework of modern life insurance mathematics

Ekonomski Vjesnik, 2013
In the traditional actuarial life insurance mathematics, liabilities to beneficiaries (technical reserves) are calculated based on conservative assumptions of mortality and interest rates. However, this approach was found to be incomplete since it does

Fractional Norms and Quasinorms Do Not Help to Overcome the Curse of Dimensionality

Entropy, 2020
The curse of dimensionality causes the well-known and widely discussed problems for machine learning methods. There is a hypothesis that using the Manhattan distance and even fractional lp quasinorms (for p less than 1) can help to overcome the curse of ...

Bayesian inverse ensemble forecasting for COVID‐19

Canadian Journal of Statistics, EarlyView.
Abstract Variations in strains of COVID‐19 have a significant impact on the rate of surges and on the accuracy of forecasts of the epidemic dynamics. The primary goal for this article is to quantify the effects of varying strains of COVID‐19 on ensemble forecasts of individual “surges.” By modelling the disease dynamics with an SIR model, we solve the ...

HPV Testing Versus Cytology for Cervical Cancer Screening Among Women 50 Years and Older: Evidence From the HPV FOCAL Randomized Controlled Trial

International Journal of Cancer, EarlyView.
ABSTRACT Evidence on the comparative effectiveness of HPV testing versus cytology specifically in women aged ≥ 50 years who are approaching screening cessation remains limited. This analysis included 6471 women aged ≥ 50 at baseline screening in the HPV FOCAL randomized clinical trial. Women were randomly allocated to receive cytology (Control Group, n

Nordgren PINNs to VQE: Advancing Hydraulic Fracturing Simulations in Shale Reservoirs

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT This study advances hydraulic fracturing simulations in shale reservoirs using two computational paradigms, Physics‐Informed Neural Networks (PINNs) and the Variational Quantum Eigensolver (VQE). PINNs were employed to solve Nordgren's equation, which governs fracture width evolution, by embedding physical laws into the neural network ...

Tactical and Strategic Risks From Supply Disruptions in Competing Supply Chains

Naval Research Logistics (NRL), EarlyView.
ABSTRACT Supply chain disruptions can lead to both tactical (i.e., loss of short‐term sales during a disruption) and strategic (i.e., loss of long‐term market share) consequences. We model the impact of a supply disruption on competing supply chains in which two firms compete for a limited backup supply.

Advancing SDG 13 and Net‐Zero Emissions in Europe: The Role of Green Technology Innovation, Renewable Energy, Environmental Taxation and Trade Openness

Sustainable Development, EarlyView.
ABSTRACT The European Union (EU) has set ambitious climate goals, aiming to become the first climate‐neutral continent by 2050, with a focus on achieving net‐zero emissions and advancing United Nations Sustainable Development Goal (SDG) 13. A key component of this transition is the role of green technological innovation, the deployment of clean energy ...
