Recent challenges in actuarial science

P Embrechts, MV Wüthrich - Annual Review of Statistics and Its …, 2022 - annualreviews.org
For centuries, mathematicians and, later, statisticians, have found natural research and
employment opportunities in the realm of insurance. By definition, insurance offers financial …

Collective reserving using individual claims data

Ł Delong, M Lindholm, MV Wüthrich - Scandinavian Actuarial …, 2022 - Taylor & Francis
The aim of this paper is to operationalize claims reserving based on individual claims data.
We design a modeling architecture that is based on six different neural networks. Each …

Fitting censored and truncated regression data using the mixture of experts models

TC Fung, AL Badescu, XS Lin - North American Actuarial Journal, 2022 - Taylor & Francis
The logit-weighted reduced mixture of experts model (LRMoE) is a flexible yet analytically
tractable non-linear regression model. Though it has shown usefulness in modeling …

Individual claims reserving using the Aalen–Johansen estimator

M Bladt, G Pittarello - ASTIN Bulletin: The Journal of the IAA, 2025 - cambridge.org
We propose an individual claims reserving model based on the conditional Aalen–
Johansen estimator, as developed in Bladt and Furrer ((2023a) arXiv: 2303.02119.). In our …

Copula-based Modeling for IBNR Claim Loss Reserving

S Zaroudi, MR Faridrohani, MH Behzadi… - arXiv preprint arXiv …, 2022 - arxiv.org
There are growing concerns for reserves estimation of incurred but not reported (IBNR)
claims in actuarial sciences. In this paper, we propose a copula-based dependency model …

Stochastic reserving using policyholder information via EM algorithm

Z Wang, W Liu - Applied Mathematical Modelling, 2022 - Elsevier
In stochastic reserving, the incurred outstanding liabilities of general insurance companies
result in incomplete claims because of truncation and censoring. It is necessary for …

Combined modelling of micro-level outstanding claim counts and individual claim frequencies in non-life insurance

A Bücher, A Rosenstock - European Actuarial Journal, 2024 - Springer
Usually, the actuarial problems of predicting the number of claims incurred but not reported
(IBNR) and of modelling claim frequencies are treated successively by insurance …

Combined modelling of micro-level outstanding claim counts and individual claim frequencies in general insurance

A Bücher, A Rosenstock - Available at SSRN 4564502, 2023 - papers.ssrn.com
Usually, the actuarial problems of predicting the number of claims incurred but not reported
(IBNR) and of modelling claim frequencies are treated successively by insurance …

A Continuous Granular Model for Stochastic Reserving with Individual Information

Z Wang, W Liu - Symmetry, 2022 - mdpi.com
This paper works on the claims data generated by individual policies which are randomly
exposed to a period of continuous time. The main aim is to model the occurrence times of …

Advances in claims reserve modelling

G Pittarello - 2024 - iris.uniroma1.it
In the non-life insurance industry, insurance companies are required by local and
international regulators to set aside an amount, known as the claims reserve, to meet future …
