@MarylynRitchie Congratulations Marylyn! This is amazing!

Congratulations Marylyn!!…

Nice! I will download and try it out.…

"We categorised a continuous variable, then entered the categorised variable as a continuous variable in our regression model." Very cool. Retweeted by Ruowang Li, PhD

The Cava lab is up and running! We're recruiting a post-doc to study the interpretabilty and fairness of clinical ML models. Please share!… Retweeted by Ruowang Li, PhD

The extent and impact of mislabeled test-set data in ML is astounding. Apparent model improvement is often via better fitting of test errors. New method for efficiently finding errors in large test sets. We need to apply this to biomedical datasets… Retweeted by Ruowang Li, PhD

Agree. But PRS research is just getting started. It should have more clinical impact in the future.…
