However, predictions of expected mortality are sensitive to model assumptions. Among three specifications of a Serfling-Poisson regression for seasonal mortality, we analyse which one yields the most accurate predictions. We compare the Serfling-Poisson models with: 1) parametric effect for the trend and seasonality (SP), 2) non-parametric effect for the trend and seasonality (SP-STSS), also known as modulation model, and 3) non-parametric effect for the trend and parametric effect for the seasonality (SP-STFS). Forecasting is achieved with P-splines smoothing. The SP-STFS model resulted in more accurate historical forecasts of monthly rates from national statistical offices in 25 European countries. An application to the COVID-19 pandemic years illustrates how excess mortality can be used to evaluate the vulnerability of populations and aid public health planning.","url_abs":"https://arxiv.org/abs/2502.10787v1","url_pdf":"https://arxiv.org/pdf/2502.10787v1.pdf","source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28","licence_url":"https://creativecommons.org/licenses/by-sa/4.0/legalcode","row_kind":"links_only","authors_date_abstract":"arXiv metadata, CC0 1.0 (https://info.arxiv.org/help/license), from the Kaggle arXiv metadata snapshot of 2026-09-12"},"code_links":[{"paper_slug":"modelling-and-short-term-forecasting-of","repo_url":"https://github.com/AinhoaLeger/Shortcasting-Seasonal-Mortality","is_official":1,"mentioned_in_paper":0,"mentioned_in_github":0,"framework":"none","reach":null}],"tasks":[],"methods":[],"datasets_introduced":[],"methods_introduced":[],"results":[],"syntology":{"atlas_url":null,"mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
