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 GravityKit?

GravityKit's exporter stops producing files and starts keeping a spreadsheet in sync.

GravityKit ships weekly across a suite of Gravity Forms add-ons, publishing a Launch Log digest alongside dedicated announcements for the larger items. This window covers Google Sheets export in GravityExport, unions in Multiple Forms, rich text inline editing in GravityEdit, and a long tail of Gravity Forms 3.0 and WordPress 7.0 compatibility fixes.

gkwdist vs GravityKit: editorial side-by-side

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.

6.3

GravityKit's exporter stops producing files and starts keeping a spreadsheet in sync.

◆ Current state

GravityKit ships weekly across a suite of Gravity Forms add-ons, publishing a Launch Log digest alongside dedicated announcements for the larger items. This window covers Google Sheets export in GravityExport, unions in Multiple Forms, rich text inline editing in GravityEdit, and a long tail of Gravity Forms 3.0 and WordPress 7.0 compatibility fixes.

◆ Where it's heading

The suite is shifting from displaying form data to moving it. Unions stack entries from several forms into one View, Google Sheets export keeps an external sheet current, and the MCP add-ons in the same window expose theme and entry data to agents. Taken together, Gravity Forms entries are being treated as a data source other systems consume rather than something rendered on a WordPress page.

◆ Prediction

Expect additional live-sync destinations following the Google Sheets pattern, and continued compatibility work while Gravity Forms 3.0 and WordPress 7.0 adoption spreads.
