EXTREME GALTON now also contains a "LEARN" mode to run simulations and learn more about sampling and the central limit theorem.

No bazookas though...

Laser gates!

Please do note that blowing up outliers with a bazooka is considered a questionable research practice!

After 150 years of boring wooden Galton boards, I finally fixed it!

Now with lasers, bazookas, bombs, pinball bumpers, and extremely serious sci-fi hamsters.

Thrilled to share that our work (with Sverre Urnes Johnson and @sachaepskamp.bsky.social) on invariance partial pruning (IVPP), a novel approach to comparing networks in time-series and panel data is now online at Psychological Methods 10.1037/met0000824 (preprint link: 10.31234/osf.io/vb8dz_v2).

mlVAR: Multi-Level Vector Autoregression Estimates the multi-level vector autoregression model on time-series data. Three network structures are obtained: temporal networks, contemporaneous networks and between-subjects networks.

mlVAR #Rstats 📦 version 0.6.1 is now on CRAN! Major updates include the mlGGM function for multi-level GGM estimation on nested cross-sectional data (e.g., students nested in classrooms) and the inclusion of residuals + predicted values from the mlVAR results. cran.r-project.org/web/packages...

The largest #Rstats 📦psychonetrics update so far is on its way to CRAN!

Last day of AMPC 2026 at NUS — the first time this conference was held in Asia! Thank you to all the speakers, participants, co-organizers, and volunteers for an incredible three days.
