Fiscal vs logbin
A side-by-side editorial comparison of Fiscal and logbin — release velocity, themes, recent moves, and the top alternatives to consider.
Fiscal vs logbin: at a glance
What is Fiscal?
UK income tax calculations reach CRAN, then go quiet behind pointer-only release notes.
Fiscal computes UK income tax. It reached its 1.0.0 milestone in March 2026 and shipped two patch releases in the fortnight after, then stopped. The GitHub release bodies carry no changelog of their own: each one points at the NEWS file and the CRAN page, so the feed shows cadence but not content.
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.

UK income tax calculations reach CRAN, then go quiet behind pointer-only release notes.
◆ Current state
Fiscal computes UK income tax. It reached its 1.0.0 milestone in March 2026 and shipped two patch releases in the fortnight after, then stopped. The GitHub release bodies carry no changelog of their own: each one points at the NEWS file and the CRAN page, so the feed shows cadence but not content.
◆ Where it's heading
Three releases in a fifteen-day window reads as post-publication cleanup rather than a development push, which is the normal shape after a first CRAN acceptance. Because every body is the same boilerplate, direction has to be read from the tags alone, and the tags say only that two patches followed the 1.0.0 line.
◆ Prediction
The most likely next release is an annual one tracking a new UK tax year's rates and thresholds. The release notes as published give no evidence for anything beyond that.

Relative-risk regression that converges where glm fails, under an unreadable tag order
◆ 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.

Frequently asked questions
What is the difference between Fiscal and logbin?
They serve adjacent needs but don't currently overlap on shipped themes. Fiscal and logbin 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 Fiscal better than logbin?
Sparkpulse doesn't pick a winner — we score release velocity, not feature parity. Fiscal and logbin are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band).
