How to optimise tournament draws: The case of the FIFA World Cup
Abstract The organisers of major sports competitions use different policies with respect to constraints in the group draw. Our paper aims to rationalise these choices by analysing the trade‐off between attractiveness (the number of games played by teams from the same geographic zone) and fairness (the departure of the draw mechanism from a uniform ...

ABSTRACT A key component for wildfire risk management is predicting when and where fires might happen. We build short‐term (1–4 days ahead) fire occurrence prediction models by adapting the random forest algorithm using an errors in variables approach to account for the inherent forecasting error in short‐term forecasts of fuel moisture.

Tail Risk Transmission in Agricultural and Energy Markets
ABSTRACT This paper examines downside hedging, tail diversification, and extreme tail risk transmission between crude oil and agricultural commodity futures over two decades. We develop complementary indicators of downside dependence, including sign‐switching frequency and persistence, to assess tail risk dynamics, hedging effectiveness, and associated

Lee-Carter mortality forecasting: methodological and computational issues [PDF]
In this thesis we describe relevant aspects of the development of survival modelling in actuarial mathematics. In particular we introduce some recent mortality projection models and research dealing with uncertainty in future trends and we review the ...

Bi‐Model Deep Learning Architectures: A Systematic Review of Fusion Strategies and Design Taxonomies
ABSTRACT Bi‐model deep learning, the coordinated use of two complementary models or modalities, has emerged as a powerful paradigm for improving predictive accuracy and robustness in complex real‐world applications. However, existing research remains scattered across domain‐specific studies, with no unified account of the architectural patterns, fusion

Predictions of Success in the Actuarial Major [PDF]
This study finds predictive factors that have a significant effect on the ending Mathematics/Actuarial GPA of Actuarial majors at Bryant University. This was done to add clarity to incoming students for what it takes to do well in the actuarial major ...

The Role of Variance Risk Premium in Derivative Pricing: Modeling, Estimation and Impact
ABSTRACT This paper estimates a model where variance risk premiums (VRP) is not fully explained by equity risk premiums (ERP). This separation can be detected thanks to a new breed of GARCH models with enough innovations to disconnect returns from variances. This type of risk‐neutralization is compatible with continuous‐time settings.

Two‐Stage Estimation for Causal Inference Involving Semi‐Continuous Exposures
ABSTRACT Methods for causal inference are well developed for binary and continuous exposures, but in many settings, the exposure has a substantial mass at zero—such exposures are called semi‐continuous. We propose a general causal framework for such semi‐continuous exposures, together with a two‐stage estimation strategy.
