What is animation?

Contribution-driven maintenance on a package whose last structural change was magick support.

animation renders statistical and mathematical animations from R to GIF, HTML, video and LaTeX. The most recent release adds a single contributed demo; the substantive work — magick-based conversion and resolution control — landed in the 2.6/2.7 pair. Several entries carry near-identical import timestamps, so the visible dates compress the real release history.

What is loo?

loo keeps rewriting the diagnostics Bayesian modellers read off model comparison

loo computes leave-one-out cross-validation and model comparison for Bayesian models in the Stan ecosystem. Two releases in this window changed what users actually read: 2.7.0 replaced the fixed Pareto-k thresholds with sample-size-dependent ones and dropped the middle category, and 2.10.0 reshaped loo_compare's output into a data.frame with new uncertainty columns. The releases between are diagnostic robustness fixes and moment-matching corrections.

Contribution-driven maintenance on a package whose last structural change was magick support.

◆ Current state

animation renders statistical and mathematical animations from R to GIF, HTML, video and LaTeX. The most recent release adds a single contributed demo; the substantive work — magick-based conversion and resolution control — landed in the 2.6/2.7 pair. Several entries carry near-identical import timestamps, so the visible dates compress the real release history.

◆ Where it's heading

The package has settled into contribution-driven maintenance: outside users file demos and device fixes, and the maintainer merges them. The direction set in 2.6 — dropping the shell-out to an external ImageMagick install in favour of the magick R package — was the last structural change. Nothing in the entries suggests a redesign is underway.

◆ Prediction

Expect the next release to be another accepted contribution — a demo or a device-specific fix — rather than a change to how animations are produced.

loo keeps rewriting the diagnostics Bayesian modellers read off model comparison

◆ Current state

loo computes leave-one-out cross-validation and model comparison for Bayesian models in the Stan ecosystem. Two releases in this window changed what users actually read: 2.7.0 replaced the fixed Pareto-k thresholds with sample-size-dependent ones and dropped the middle category, and 2.10.0 reshaped loo_compare's output into a data.frame with new uncertainty columns. The releases between are diagnostic robustness fixes and moment-matching corrections.

◆ Where it's heading

The package is being brought in line with the current PSIS literature rather than extended with new features, and the practical effect is that the numbers practitioners quote in papers keep changing meaning. Work is increasingly delegated to posterior for shared computations, and the project has added contributor process, benchmarks and a published AI contribution policy.

◆ Prediction

Expect further work on comparison diagnostics — the p_worse and diag_* columns are new enough that their defaults and documentation will likely be revised next.
