Statistics and Science! We'll see what else I can bring in.

ggRandomForests 3.4.0 on CRAN. varPro partial plots now default to a readable y-axis: probability for classification, survival S(τ) for survival, not ensemble mortality. Plus unsupervised varPro: variable selection with no outcome.

Back in May I gave a talk at R/Medicine 2026: “Care and Feeding of Your Biostats Team.” The recording is now up — Quarto, renv, internal R packages, automated checks. Turning tribal knowledge into shared practice. 🎙️

TemporalHazard 1.1.0 on CRAN. Survival after surgery isn't one rate: high early, flat in the middle, rising late. TemporalHazard models fit all three at once. 1.1.0 adds weights, interval censoring, and per-phase confidence limits on predictions. #rstats https://t.co/a5yDxWqfOu

ggRandomForests 3.1.0 on CRAN. RF importance usually means permutation: shuffle a column, watch OOB error climb. But that's fake data when predictors correlate. 3.1.0 wraps varPro — importance from the forest's own rules, on real data, in ggplot2.

🎉 TemporalHazard is on CRAN!

Native R implementation of the multiphase parametric hazard model. This will decompose your hazard model into early/constant/late framework used in cardiothoracic surgery outcomes for 40 years.

Excited to share our paper in @Nature: We revisit the 50+ year-old maths problem with AI: how efficiently can we multiply two matrices? Surprisingly, the answer is still not known - even for 3x3 matrices! With AI, we discover many new efficient and exact algorithms. 1/13

@tylergbyers @5sigma @_brohrer_ As did I.

[John Ehrlinger @JohnEhrlinger]

@_brohrer_ Well, it makes sense. Community and all.

@jwbelmon @KimMaida FORTRAN66… cause in the early 80s, 77 wasn’t trusted yet?

@davidfowl I feel this.

New Single Release Day!

Hummingbird is Matt's creation, a groove based instrumental that has both rock and jazz roots. Progressive metal that switches feel through out the entire song.
