stat.ME2025

Bayesian variable selection in a Cox proportional hazards model with the "Sum of Single Effects" prior

Yunqi Yang, Karl Tayeb, Peter Carbonetto +3

Motivated by genetic fine-mapping applications, we introduce a new approach to Bayesian variable selection regression (BVSR) for time-to-event (TTE) outcomes. This new approach is…
