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.

What is sd2r?

Local Stable Diffusion inference lands in R, shipped as Rcpp bindings over stable-diffusion.cpp

sd2r is a young project wrapping stable-diffusion.cpp for R via Rcpp. The 0.1.0 release established the package structure and the core call surface — sd_ctx(), sd_txt2img(), sd_save_image() — with Vulkan GPU support behind a configure flag and a worked SD 1.5 example at 512x512. The two releases since are not code but asset bundles: precompiled tokenizer vocabularies and BPE merge tables shipped as header files, growing from four tokenizers to twelve.

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.

Local Stable Diffusion inference lands in R, shipped as Rcpp bindings over stable-diffusion.cpp

◆ Current state

sd2r is a young project wrapping stable-diffusion.cpp for R via Rcpp. The 0.1.0 release established the package structure and the core call surface — sd_ctx(), sd_txt2img(), sd_save_image() — with Vulkan GPU support behind a configure flag and a worked SD 1.5 example at 512x512. The two releases since are not code but asset bundles: precompiled tokenizer vocabularies and BPE merge tables shipped as header files, growing from four tokenizers to twelve.

◆ Where it's heading

The asset releases are the more revealing half of this history. The first bundle covered CLIP, Mistral, Qwen and UMT5 — enough for SD 1.x through Flux. The second adds T5, Gemma, Gemma2 and GPT-OSS merges and splits UMT5 out as the Wan video encoder, so the tokenizer surface now reaches well beyond the image models the package currently exposes. Vocabulary support is being staged ahead of the inference paths that would use it.

◆ Prediction

Given that tokenizers for Flux, SD3 and the Wan video encoder are already bundled while the documented API stops at txt2img, the next step is most likely exposing those model families through the R interface.
