ardlverse vs stringi: at a glance
What is ardlverse?
An outside audit against Stata found seven errors in ardlverse's panel estimator, including regressions with no intercept.
A small R package for autoregressive distributed lag models, with only three releases on record. The first two were administrative — a CRAN version note and a Zenodo metadata update. The third, 2.0.0, is a correction release built entirely from an external audit of panel_ardl() against Stata's xtpmg, and it is the only entry here with substantive content.
What is stringi?
stringi has spent two years on build hardening since its Unicode 15.1 reset.
stringi is the ICU-backed string engine under a large share of R's text handling. Since the 1.8.1 reset in late 2023 — which bundled ICU 74.1, dropped Solaris, and raised the compiler floor — every subsequent release has been build and portability maintenance: PROTECT-stack fixes, Windows build errors, compiler warnings. The 1.8.8 release in July 2026 continues that pattern by dropping the configure script's C++11 fallback.

ardlverse
0.0ANALYTICS
An outside audit against Stata found seven errors in ardlverse's panel estimator, including regressions with no intercept.
◆ Current state
A small R package for autoregressive distributed lag models, with only three releases on record. The first two were administrative — a CRAN version note and a Zenodo metadata update. The third, 2.0.0, is a correction release built entirely from an external audit of panel_ardl() against Stata's xtpmg, and it is the only entry here with substantive content.
◆ Where it's heading
The package's direction is now set by verification against an established reference implementation rather than by feature work. The seven fixes bring panel_ardl() into strict alignment with the original Pesaran, Shin and Smith framework, and the most serious of them is structural: internal regressions used lm.fit(), which unlike lm() does not append an intercept, so every short-run regression across the PMG, MG and DFE estimators was forced through the origin. Design matrices now carry a column of ones and DFE reconstructs the grand-mean intercept to match standard fixed-effects output.
◆ Prediction
Expect the next releases to extend the same audit approach to the remaining estimators, since a package that has been validated against xtpmg on one function invites the same question about the rest.
stringi
2.5ANALYTICS
stringi has spent two years on build hardening since its Unicode 15.1 reset.
◆ Current state
stringi is the ICU-backed string engine under a large share of R's text handling. Since the 1.8.1 reset in late 2023 — which bundled ICU 74.1, dropped Solaris, and raised the compiler floor — every subsequent release has been build and portability maintenance: PROTECT-stack fixes, Windows build errors, compiler warnings. The 1.8.8 release in July 2026 continues that pattern by dropping the configure script's C++11 fallback.
◆ Where it's heading
The package has reached feature stability and is maintained as infrastructure. Releases arrive when a toolchain, platform, or check regime changes, not when users ask for capability. The two-and-a-half year gap between 1.8.1's Unicode bump and anything comparable suggests the next directional move will again be an ICU bundle refresh rather than new API surface.
◆ Prediction
The next release is most likely another build-time fix or an ICU bundle update to a newer Unicode version; the entries show no in-progress feature work.
