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.

What is wooldridge?

A textbook data package whose whole job is to stay installable, and whose releases prove how much work that is.

wooldridge ships the datasets from Wooldridge's Introductory Econometrics so students can load any of them with one command. The data has been essentially complete since the 7th-edition sets landed in 1.4-1; every release since has been about keeping the package on CRAN. The most recent tag exists only to re-run roxygen2 so that documentation URL fixes from the previous version actually reached the .Rd files.

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.

0.0

A textbook data package whose whole job is to stay installable, and whose releases prove how much work that is.

◆ Current state

wooldridge ships the datasets from Wooldridge's Introductory Econometrics so students can load any of them with one command. The data has been essentially complete since the 7th-edition sets landed in 1.4-1; every release since has been about keeping the package on CRAN. The most recent tag exists only to re-run roxygen2 so that documentation URL fixes from the previous version actually reached the .Rd files.

◆ Where it's heading

The maintainer has been systematically shrinking the package's attack surface for years. Dependencies used only for vignette examples were cut after one of them broke its API and triggered a CRAN removal notice; test infrastructure moved from testthat to tinytest and from Travis and AppVeyor to GitHub Actions; datasets were compressed by stripping attributes left over from the Stata imports. The stated goal, written into the 1.4-2 notes, is that this should be the easiest package the maintainer has to look after.

◆ Prediction

Nothing in the recent entries points to new data; the next release will most likely be triggered by another CRAN check failure or by a new edition of the textbook adding datasets.
