logbin vs rvMF
A side-by-side editorial comparison of logbin and rvMF — release velocity, themes, recent moves, and the top alternatives to consider.
logbin vs rvMF: at a glance
What is logbin?
Relative-risk regression that converges where glm fails, under an unreadable tag order
logbin fits log-binomial models to estimate relative risk, a fit standard glm frequently fails to converge on because of the constrained parameter space. Its answer is a choice of algorithms — adaptive barrier, combinatorial EM, and expectation-maximisation on an overparameterised model — selected through a method argument and optionally accelerated with turboEM. The most recent release, in April 2025, replaces the variance-covariance calculation in summary.logbin so it matches summary.glm, and adds a testthat suite.
What is rvMF?
A fast von Mises-Fisher sampler that ships a citation more often than a feature.
rvMF generates pseudo-random vectors from the von Mises-Fisher distribution, the standard model for directional data on a sphere. Its released surface has not changed materially in the window: the three most recent tags cover a dropped dependency, a citation update, and a C++ linking correction. The February 2026 release removes the scModels import.

◆ Current state
logbin fits log-binomial models to estimate relative risk, a fit standard glm frequently fails to converge on because of the constrained parameter space. Its answer is a choice of algorithms — adaptive barrier, combinatorial EM, and expectation-maximisation on an overparameterised model — selected through a method argument and optionally accelerated with turboEM. The most recent release, in April 2025, replaces the variance-covariance calculation in summary.logbin so it matches summary.glm, and adds a testthat suite.
◆ Where it's heading
The method work concluded in 2021 and the package has since been aligned with base R conventions rather than extended: the vcov calculation now mirrors glm's, and earlier releases added the contrasts, qr, R and effects components so standard glm S3 methods such as influence() and plot() work on logbin objects. Be warned that the feed's tag order is unusable — versions 2.0, 2.0.1, 2.0.2 and 2.0.4 were all pushed within ninety seconds on 23 July 2021 in non-monotonic order, while 2.0.3 carries a 2017 timestamp and restates 2.0.2's notes. Read the bodies, not the sequence.
◆ Prediction
Expect continued alignment with glm conventions and occasional CRAN maintenance; the algorithm set has been stable for four years and nothing in these entries suggests another is planned.
rvMF
0.0INFRA · APIS
A fast von Mises-Fisher sampler that ships a citation more often than a feature.
◆ Current state
rvMF generates pseudo-random vectors from the von Mises-Fisher distribution, the standard model for directional data on a sphere. Its released surface has not changed materially in the window: the three most recent tags cover a dropped dependency, a citation update, and a C++ linking correction. The February 2026 release removes the scModels import.
◆ Where it's heading
This is a single-purpose sampler that reached its intended scope early and has been maintained rather than extended since. The visible work is dependency reduction and paper-and-citation housekeeping, which is the normal shape for a method package whose implementation is described in a published paper and whose correctness argument lives there rather than in the changelog.
◆ Prediction
More of the same: occasional releases to keep the C++ layer building and the dependency list short. Nothing in the notes points toward new distributions or new sampling methods.

Frequently asked questions
What is the difference between logbin and rvMF?
They serve adjacent needs but don't currently overlap on shipped themes. logbin and rvMF are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band). See the at-a-glance table above for a side-by-side breakdown of velocity, recent sparks, and editorial themes.
Is logbin better than rvMF?
Sparkpulse doesn't pick a winner — we score release velocity, not feature parity. logbin and rvMF are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band).
