@drizopoulos.bsky.social and I have written a tutorial on extended joint models for longitudinal and time-to-event data. Using JMbayes2, we cover models with multiple longitudinal outcomes, flexible association structures, recurrent events, competing risks, and multistate processes.

Extended Joint Models for Longitudinal and Time-to-Event Data: A Tutorial
Shared-parameter joint models for longitudinal and time-to-event data are powerful tools for analyzing repeatedly measured biomarkers, clinical events, and the complex relationships between them. Rece...

Excited to be teaching a course at the International Biometric Conference in Seoul on Dynamic Predictions for Longitudinal and Survival Data, with applications in R using JMbayes2. Want to learn how to build and interpret dynamic predictions from joint models? Check: www.ibc2026.org/events/short...

Our new paper is out in Statistics in Medicine! We developed a joint model for multiple (un)bounded longitudinal markers, recurrent events, and competing risks, applied to US CF patient registry data. Joint work with @drizopoulos.bsky.social and @erandrinopoulou.bsky.social. doi.org/10.1002/sim....

A Joint Model for (Un)Bounded Longitudinal Markers, Competing Risks, and Recurrent Events Using Patient Registry Data
Joint models for longitudinal and survival data have become a popular framework for studying the association between repeatedly measured biomarkers and clinical events. Nevertheless, addressing compl...
