My talk from posit::conf earlier this fall on getting unstuck with #Python is now available to watch!

- Ten years ago, I attempted to learn Python and it went EXTRMELY badly 😩
- I am really happy that so much tooling in this area has improved SO much since then 😌

Dr. Cat Hicks (@grimalkina.bsky.social) gave one of my very favorite keynotes of all time at #positconf this year 🥹 It really made my heart glow, and now that all the conf talks are on YouTube, you can watch it even if you missed conf!! #databs #rstats #python

I built a DAG diagram with garden hoses for teaching.
Pictured: a collider bias diagram, inspired by a blocked pipe situation I experienced (which I credit with giving me the intuition though it also ruined my belongings in the flooded cellar).

Have you ever wondered how the transportability of an estimate may be affected by the choice of effect measure?

Join us in Nov to hear from @mpiccininni3.bsky.social on why the causal risk ratio might be more stable and transportable across settings.
