S207 - On similarity-based models for Bayesian disease mapping
Tuesday October 6, 2026 09:30 - 10:00 UTC
In the 1970s, the conditionally formulated Gaussian Markov random field (GMRF), known as the conditional autoregressive (CAR) model, was introduced in line with Tobler’s first law of geography: "everything is related to everything else, but near things are more related than distant things." The CAR model uses W, the well-known adjacency matrix that encodes the neighbourhood structure of a spatial lattice (e.g., two areas are neighbours if they share a common border).
Since its introduction, the CAR model has undergone many adaptations, with numerous adaptive models proposed in the literature. However, almost all of these models (to the best of our knowledge, all except ours) still adhere to Tobler’s law. Yet, much of the data collected today – often aggregated at the areal level for confidentiality or other reasons – does not necessarily follow this law.
In this talk, we will show that any extra information representing causes of or correlated with the phenomenon of interest can be used to define a similarity structure, rather than relying solely on geographical neighbourhoods. Using simulated data, we illustrate that similarity-based structures can be more effective than traditional neighbourhood-based structures for smoothing both local and global risks. We will show that the correct identification of high- and low-risk areas, crucial for public health planning and resource allocation, is better achieved when the similarity-based structure is used.

S115 - Reliable Variable Selection for Biomedical Data Science: From Shrinkage Estimation to Interpretable Learning
Tuesday October 6, 2026 13:30 - 14:00 UTC
Modern biomedical data science increasingly relies on datasets with many predictors, limited sample sizes, and complex correlation structures. In these settings, classical regression and standard variable-selection methods may lead to unstable models, overfitting, or conclusions that are difficult to interpret. Shrinkage and penalized estimation provide a principled framework for improving reliability, but their success depends on how multicollinearity and dependence among predictors are handled. This talk discusses reliable variable selection for biomedical data science, moving from classical shrinkage ideas to modern interpretable learning. The presentation will introduce the motivation behind ridge-type methods, LASSO-based procedures, elastic net estimation, and adaptive penalization, with emphasis on approaches that use correlation information to improve model stability and interpretability. Motivated by biomedical applications such as molecular subtype identification and classification problems, the talk will show how statistically grounded regularization can support both prediction and scientific interpretation. The broader message is that reliable biomedical data science requires methods that are not only accurate, but also stable, transparent, reproducible, and interpretable for domain experts.

S118 - Data, Diversity, and Dialogue: Women Shaping the Future of Statistics and Data Science
Tuesday October 6, 2026 15:00 - 16:00 UTC
At a time when data drives decisions across science, industry, and society, the voices shaping this landscape matter more than ever. This invited session brings together distinguished women researchers whose work reflects the power of diversity, collaboration, and intellectual curiosity in statistics and data science.

Through their journeys, the speakers will illustrate how meaningful connections—across disciplines, institutions, and cultures—emerge not only from shared research goals but also from openness, mentorship, and resilience. Their experiences reveal how collaborative environments can spark innovation, amplify impact, and create pathways for future generations of women in the field.

More than a showcase of research, this session is an invitation to reflect on how we build scientific communities that are inclusive, dynamic, and forward-looking. By fostering dialogue and embracing diverse perspectives, we strengthen our collective ability to tackle complex challenges and shape a more connected and equitable future for data science.

This session celebrates the role of women as catalysts for change, bridging ideas and people to advance knowledge and inspire the next generation.

This session is sponsored by the Portuguese Statistical Society an by the Portuguese Country Representative of CWS.
