March 15 - No meeting due to ENAR! 

March 20 (11 am - 1 pm, University Office Plaza, UOP 351 Skylab Conf Rm, in person only)

Watch a short course, "Cure Models in Survival Analysis" by Dr. Ingrid Van Keilegom sponsored by the ASA/Lifetime Data Science Section. (Note that this is not at our usual Friday meeting time and that we do not plan to make this meeting hybrid as usual. If you cannot make it in person, feel free to register the short course and watch it yourself. We plan to discuss the short course content at the next meeting.)

• Link to a review paper, of which Dr. VK is also an author.

• Link to Han's note on the short course on Notion.

March 29 (10 am, University Office Plaza, UOP 2-254 Fishbowl Conf Rm and Zoom, hybrid)

Topic: Han Lu will present on "Machine Learning Meets Survival: Detecting Heterogeneous Treatment Effect with Observational Data."

Reference: 

• Hu et al. 2021: doi.org/10.1002/sim.9090 

April 12 (9:00-11:00 am, UOP 2-254 Fishbowl Conf Rm)

We plan to watch a WebENAR about missing data imputation together, "When to Include the Outcome in Your Imputation Model: A Mathematical Demonstration and Practical Advice." You can also register (free for ENAR members) and watch the webinar on your own.

Reference: 

• Link to the speaker's website (Dr. Lucy D'Agostino McGowan) with slides attached.

• Link to the speaker's preprint "The 'Why' behind including 'Y' in your imputation model" on which the WebENAR talk was based. 

• Link to the vignette of package "brms" the other speaker (Prof. Frank E. Harrell) mentioned and used as examples of the Bayesian approach in data imputation.

• Link to Han's note on the WebENAR on Notion.

April 26 (10:00-11:00 am, UOP 2-254 Fishbowl Conf Rm and Zoom)

Topic: Nitya Shah will talk about her current research - longitudinal and causal inference! Specifically, she will introduce us to the causal framework covered in Young et al. 2020 for classical estimands in survival settings with competing events.

Reference: Young et al. 2020: onlinelibrary.wiley.com/doi/10.1002/sim.8471 

May 10 (11:00 am, UOP 2-254 Skylab Conf Rm)

We plan to host an end-of-semester potluck party! Come and join us even if you missed all the interesting events earlier in this semester ;) Bring your plus one (or more) and let's bond over statistics!  Please fill out this form if you are planning on joining!
