What is metagroup?

A first release that turns meta-analytic heterogeneity into interpretable subgroups.

metagroup reached CRAN in late August with a complete first release: eight grouping functions covering binary, continuous, correlational, proportion, incidence and generic inverse-variance data, plus interpretation and plotting on top. The two releases since are CRAN review housekeeping. The package has shipped nothing but its launch.

What is midr?

A black-box interpreter reaches CRAN, then learns multi-class and survival responses

midr explains black-box models by fitting an interpretable surrogate through Maximum Interpretation Decomposition — main effects plus second-order interactions, with exact Shapley values for the surrogate. Two months after its first CRAN release it can take a matrix response, which covers multi-class classification and survival models, and hold collections of fitted interpretations in midlist and midrib objects for comparison.

A first release that turns meta-analytic heterogeneity into interpretable subgroups.

◆ Current state

metagroup reached CRAN in late August with a complete first release: eight grouping functions covering binary, continuous, correlational, proportion, incidence and generic inverse-variance data, plus interpretation and plotting on top. The two releases since are CRAN review housekeeping. The package has shipped nothing but its launch.

◆ Where it's heading

The design is a two-step pipeline, partitioning studies into homogeneous clusters and then characterising what those clusters have in common, which puts interpretation rather than detection at the centre. The follow-up releases suggest the author is still clearing the CRAN intake process rather than extending the method.

◆ Prediction

The next substantive release most likely broadens the interpretation side, since the grouping functions already cover the standard effect-size types.

A black-box interpreter reaches CRAN, then learns multi-class and survival responses

◆ Current state

midr explains black-box models by fitting an interpretable surrogate through Maximum Interpretation Decomposition — main effects plus second-order interactions, with exact Shapley values for the surrogate. Two months after its first CRAN release it can take a matrix response, which covers multi-class classification and survival models, and hold collections of fitted interpretations in midlist and midrib objects for comparison.

◆ Where it's heading

The releases move outward along two axes at once: what can be interpreted, and how much of it fits in memory. Version 0.5.3 rebuilt the fitting path to avoid materialising large design matrices and added a save.memory option; 0.6.0 widened the response from a vector to a matrix and added parametric link functions. Class and argument names were shortened in the same release, so the package is still willing to break itself this early.

◆ Prediction

With multiple models now held in one object and visualisation methods for them, comparison across models is the surface most likely to fill out next — the collection classes exist but the notes describe manipulation and plotting rather than any comparison metric.
