What is asar?

A NOAA report-template generator being debugged by the workshops that teach it.

asar generates standardized stock assessment report skeletons, with create_template() as the function everything else orbits. The visible release history is short and entirely reactive: two rounds of fixes to template customization and rerendering, then a documentation release moving the project's authoring guidelines onto the package website as living articles. Nothing in the window adds capability.

What is gkwdist?

gkwdist keeps finding that its distributions were returning the wrong numbers.

The package implements the Generalized Kumaraswamy distribution family and its sub-families. The current release fixes six numerical defects, the most serious being that dgkw() returned zero for every input because internal helpers collided with same-named functions in R's public Rmath.h header. Log-likelihoods for three sub-families were also wrong for data near zero due to clamping instead of working in log space.

asar vs gkwdist: editorial side-by-side

A
asar
INFRA · APIS
0.0

A NOAA report-template generator being debugged by the workshops that teach it.

◆ Current state

asar generates standardized stock assessment report skeletons, with create_template() as the function everything else orbits. The visible release history is short and entirely reactive: two rounds of fixes to template customization and rerendering, then a documentation release moving the project's authoring guidelines onto the package website as living articles. Nothing in the window adds capability.

◆ Where it's heading

The releases are paced by training events rather than a roadmap. The 2.0.0 rerender bugs — blank author sections, parameters not propagating into both the YAML and the params chunk, custom sections mislabelled — are the kind found by people actually filling in a template, and the follow-up hotfix names a workshop explicitly as where the problems surfaced. Moving the guidelines into versioned site articles, revised after workshop feedback, continues that: the standard is being treated as part of the software rather than a document beside it.

◆ Prediction

With a workshop series named as upcoming in the entries, the next release is most likely another round of template fixes reported from a live session rather than new report types.

2.5

gkwdist keeps finding that its distributions were returning the wrong numbers.

◆ Current state

The package implements the Generalized Kumaraswamy distribution family and its sub-families. The current release fixes six numerical defects, the most serious being that dgkw() returned zero for every input because internal helpers collided with same-named functions in R's public Rmath.h header. Log-likelihoods for three sub-families were also wrong for data near zero due to clamping instead of working in log space.

◆ Where it's heading

Every release in this window is correctness work with an unchanged public API — critical MLE fixes in 1.1.3, a CRAN timing-test patch in 1.1.4, numerical corrections in 1.1.5. The recurring theme is that analytically correct formulas were being defeated by implementation details: name collisions, sign errors returning negative infinity where positive was required, and clamping thresholds that destroyed precision in the tails. Test infrastructure added in 1.1.2 validates analytical derivatives against numerical differentiation, which is how several of these were caught.

◆ Prediction

Expect further validation-driven fixes rather than new distributions, since the derivative-checking suite added earlier is still surfacing defects in existing routines.
