Excited to be teaching a course at the IBC 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 course SC02 at ibc2026.org/events/shortcour…
New feature in 📦JMbayes2 supporting different specifications of the baseline hazard function - learn more about it here: drizopoulos.github.io/JMbaye…

Our first invited speaker @drizopoulos gave a very insightful talk on how longitudinal data can be modelled via joint models to derive dynamic predictions. His approach is illustrated by estimating metastasis risk for prostate cancer patients based on their PSA history.

Heading to Salzburg 🏞️ to present at #SAM2024. Join us in Invited Session 16 (July 10, 09:00) for insights on efficiently integrating high-dimensional data in joint models for longitudinal and time-to-event outcomes.
Joint work with @drizopoulos and @ERandrinopoulou.

Five pre-conference courses @KellyVanLancker @drizopoulos @BabakOskooei @CNakas and many others +invited sessions covering the stat of the art in biostatistics + an exciting social program (Mount Olympus, ancient Vergina, swimming etc).
Want to learn how to improve the accuracy of dynamic predictions? Have a look at our new super learning procedure for joint models: doi.org/10.1002/sim.10010

Proud of Anirudh Tomer for receiving the Hans van Houwelingen Biometry Award from @BMS_ANed for his work on personalized schedules with joint models.
Looking forward to organizing an event on this topic next year!
