What is bkmrhat?

A parallel-chain helper for bkmr that has settled into pure upkeep.

bkmrhat wraps Bayesian kernel machine regression (bkmr) so users can run and diagnose multiple MCMC chains in parallel, then combine or continue them. The functional surface has been stable since 2022, when chain-combining picked up a low-memory path and a seed-collision bug was corrected. The most recent release adds only diagnostic metadata to the package description.

What is simDAG?

simDAG grew a second simulation engine, then spent two releases surviving upstream breakage.

simDAG generates data from directed acyclic graphs, with a library of node types covering Gaussian, binomial, Poisson, negative binomial, zero-inflated, ordered regression, Cox, and Aalen models. The 1.0.0 milestone opened node_cox() to arbitrary baseline hazard functions, which lets continuous time-dependent hazards drive discrete-event simulations. The two most recent releases exist only to keep the package on CRAN through breakage in lme4 and simr.

◆ Current state

bkmrhat wraps Bayesian kernel machine regression (bkmr) so users can run and diagnose multiple MCMC chains in parallel, then combine or continue them. The functional surface has been stable since 2022, when chain-combining picked up a low-memory path and a seed-collision bug was corrected. The most recent release adds only diagnostic metadata to the package description.

◆ Where it's heading

Three releases across five years, and the newest carries no user-facing change at all. The package is in maintenance: it does what it set out to do for bkmr users, and updates now arrive only when CRAN or an upstream dependency forces them.

◆ Prediction

Expect the next release to be another compliance or dependency-driven patch rather than new functionality; the entries show no in-progress feature work.

2.5

simDAG grew a second simulation engine, then spent two releases surviving upstream breakage.

◆ Current state

simDAG generates data from directed acyclic graphs, with a library of node types covering Gaussian, binomial, Poisson, negative binomial, zero-inflated, ordered regression, Cox, and Aalen models. The 1.0.0 milestone opened node_cox() to arbitrary baseline hazard functions, which lets continuous time-dependent hazards drive discrete-event simulations. The two most recent releases exist only to keep the package on CRAN through breakage in lme4 and simr.

◆ Where it's heading

The package has been widening what a simulation can represent rather than deepening any one node. Networks arrived in 0.4.0 so individuals could depend on each other, discrete-event simulation in continuous time arrived in 0.5.0 as an alternative to the discrete-time engine, and 1.0.0 connected the two by letting continuous hazards feed the event-driven path. Alongside that, node types keep accumulating for outcome families the framework could not previously generate.

◆ Prediction

Expect the node library to keep expanding into outcome types the discrete-event engine can now support, though the recent releases suggest upstream dependency churn will keep consuming release slots.
