What is aniread?

aniread keeps finding that every tracker lies about coordinates in its own way.

aniread is the reader package of the animovement suite, importing output from pose-estimation and centroid trackers into aniframe objects. The 0.4.0 release standardised something every reader had been getting differently — source data using an image top-left origin is now reflected into a conventional bottom-left origin, across eleven readers. Since then the work has been Octron and BORIS specifics, and 0.5.0 extended the package past tracking data into behavioural events.

What is brglm2?

A bias-reduction package reaches 1.0 by adding an estimator built for high-dimensional logistic regression

brglm2 fits generalized linear models using mean and median bias reduction rather than plain maximum likelihood, which matters most when ML estimates are infinite or badly biased. The 0.7-0.9 line broadened coverage — negative binomial via brnb(), ordinal superiority measures, the expo() method for exponentiated parameters, add1()/drop1() so step() stops silently producing nonsense. Version 1.0.0 in August 2025 added mdyplFit(), estimating logistic regression by maximum Diaconis-Ylvisaker prior penalized likelihood with optional high-dimensional corrections. The two releases since have tuned that new path.

aniread keeps finding that every tracker lies about coordinates in its own way.

◆ Current state

aniread is the reader package of the animovement suite, importing output from pose-estimation and centroid trackers into aniframe objects. The 0.4.0 release standardised something every reader had been getting differently — source data using an image top-left origin is now reflected into a conventional bottom-left origin, across eleven readers. Since then the work has been Octron and BORIS specifics, and 0.5.0 extended the package past tracking data into behavioural events.

◆ Where it's heading

Each release reads as a catalogue of the ways a source format is imprecise: Octron omitting frames where nothing was detected, BORIS exports whose image index puts a STOP before its START, idtracker.ai renaming its leading column, Windows UNC shares reporting a false negative on read permission. The fixes share a posture of reconstructing what the format left implicit rather than passing the gap through — reinstating missing frames as all-NA rows, recovering a frame interval from time and FPS. Format support now tracks aniframe's class work closely, with 0.5.0 requiring aniframe 0.6.0 for the anievent class it produces.

◆ Prediction

get_supported_sources() was added so downstream packages can discover formats programmatically instead of hard-coding them, which suggests the next additions are more sources behind that registry rather than changes to the reader API.

A bias-reduction package reaches 1.0 by adding an estimator built for high-dimensional logistic regression

◆ Current state

brglm2 fits generalized linear models using mean and median bias reduction rather than plain maximum likelihood, which matters most when ML estimates are infinite or badly biased. The 0.7-0.9 line broadened coverage — negative binomial via brnb(), ordinal superiority measures, the expo() method for exponentiated parameters, add1()/drop1() so step() stops silently producing nonsense. Version 1.0.0 in August 2025 added mdyplFit(), estimating logistic regression by maximum Diaconis-Ylvisaker prior penalized likelihood with optional high-dimensional corrections. The two releases since have tuned that new path.

◆ Where it's heading

The package's older work assumed the classical regime where observations comfortably outnumber parameters. mdyplFit() and its hd_correction argument target the opposite case, and the follow-up releases are almost entirely about it — Pearson residuals on original responses, aliased parameter handling, the sloe() signal-strength estimator ignoring leverage-one observations. Meanwhile the older surface gets graceful-failure work: brglm_fit() now returns its latest estimates with warnings rather than aborting.

◆ Prediction

Given that 1.0.1 and 1.1.0 are both dominated by mdyplFit follow-ups while the classical path receives only robustness fixes, further work on high-dimensional corrections is the likeliest direction.
