All are welcome to the March @vicbiostat.bsky.social seminar. Lee Kennedy-Shaffer from @yalesph.bsky.social will be presenting " #Estimands, Assumptions, and the Challenges of Evaluating Policies: Lessons from Staggered Adoption" 12 March, 9:30 AEDT online. www.vicbiostat.org.au #steppedwedge

I’ve been thinking about how to find R packages by functionality when you don’t already know the package name. So over the holidays, Claude Code and I built The Warehouse: a functionality-first R package directory that helps you find packages by what they do. rwarehouse.netlify.app #rstats

Double machine learning fits an adjustment model from a confounder set using correlation and so breaks down when offered variables that have good correlation just *because* they aren't suitable adjustment variables #IWouldSimplyNotIncludeEndogenousVariables

For those of you who don't know what Ross and Robert look like..a couple of photos from my collection. I'm sure I have better ones somewhere. The BW is from 1994 when our department formally became separate from Mathematics.

it's wild that R, the ubiquitous statistical computing language, was co-created by a Māori prof (Ross Ihaka) — and yet the vast majority of scientists who use R don't know this is like inventing the toaster. possibly the largest impact of a single member of an indigenous community on modern science

Young people wonder how biostat and econometrics ended up with parallel, non-intersecting literature on so many topics. Imagine if the library copies of, say, Econometrica and Biometrika were only accessible in different buildings, potentially on different campuses

📢 New Commentary: We discuss how analytic choices impact interpretation of studies on socioeconomic health inequities. We review 1) descriptive analogues of causal estimands (à la Young et al) with competing events; 2) timescale choice; and 3) covariate adjustment. 👉 academic.oup.com/aje/advance-...

Thrilled to share our new preprint on causal ML for mediation analysis! We introduce causal ML estimators for interventional effects explicitly mapped to target trials assessing hypothetical interventions inducing distinct shifts in joint mediator distributions📊 📈🧪 #CausalSky #EpiSky

Enjoying reading a bit about "Double Machine Learning" methods for semiparametric inference (particularly impressive once you account for the state that I don't currently have a direct interest in the usual applications). Very cool stuff.

Really nice new paper by Jingyu Zhang, Oliver Lüdtke, and Alexander Robitzsch on the performance of doubly robust estimators of the ATE. A great example of clear writing and reporting, useful visualization through tables, and a review of modern literature. osf.io/5uj2f_v2
