ordbetareg vs SLmetrics: at a glance
What is ordbetareg?
A brms wrapper for bounded outcomes that keeps handing users more control over the model's internals.
ordbetareg fits ordered beta regression — outcomes bounded at both ends, with mass at the bounds — on top of brms. Each release has opened up a layer that was previously fixed: v0.5.0 added posterior predictive checks and user-specified bounds, and v0.8 added a full prior override that makes cutpoint modeling possible, plus component-wise prediction of the bottom, middle and top of the scale.
What is SLmetrics?
A young ML metrics package rewrote its own backend twice in six months chasing speed.
SLmetrics provides supervised learning evaluation metrics for R — confusion matrices, classification and regression measures, ROC and precision-recall curves — with the computation pushed into C++. After a series of pre-releases it now runs on an Armadillo backend, supports OpenMP parallelism and LAPACK/BLAS, and reports 5-20x speedups over its earlier implementations. The API has been reshaped for extensibility, with an estimator argument replacing the fixed aggregation options.

A brms wrapper for bounded outcomes that keeps handing users more control over the model's internals.
◆ Current state
ordbetareg fits ordered beta regression — outcomes bounded at both ends, with mass at the bounds — on top of brms. Each release has opened up a layer that was previously fixed: v0.5.0 added posterior predictive checks and user-specified bounds, and v0.8 added a full prior override that makes cutpoint modeling possible, plus component-wise prediction of the bottom, middle and top of the scale.
◆ Where it's heading
The direction is from a convenience wrapper toward something users can take apart. The pattern across releases is the same move repeated at greater depth: what was hard-coded becomes an argument. Documentation is expanding in step, with the vignette now covering power analysis and cutpoint modeling, which suggests the audience is being taught to use the lower-level controls rather than the defaults.
◆ Prediction
Given that priors, bounds and predicted components are now all exposed, the next release most plausibly extends the diagnostic and plotting surface rather than the model itself — though releases here are more than a year apart, so timing is unpredictable.

0.0INFRA · APIS
A young ML metrics package rewrote its own backend twice in six months chasing speed.
◆ Current state
SLmetrics provides supervised learning evaluation metrics for R — confusion matrices, classification and regression measures, ROC and precision-recall curves — with the computation pushed into C++. After a series of pre-releases it now runs on an Armadillo backend, supports OpenMP parallelism and LAPACK/BLAS, and reports 5-20x speedups over its earlier implementations. The API has been reshaped for extensibility, with an estimator argument replacing the fixed aggregation options.
◆ Where it's heading
Every release in this timeline is about making the same metrics compute faster or compose better. The backend moved from Rcpp to plain C++, gained OpenMP, then was ported wholesale from Eigen to Armadillo with heavy templating. In parallel the author has been widening the API's joints: generic S3 signatures, an extensible estimator argument, and function signatures loose enough that wrapping packages can rename arguments. Bundled datasets and embedded formulas in the docs point at teaching and benchmarking use. The package still labels itself pre-release, which is consistent with how freely it has broken argument names along the way.
◆ Prediction
A stable non-pre-release version is the natural next step now that the backend has settled on Armadillo, though the repeated willingness to rename arguments suggests more API churn may come first.
