ardlverse vs biocro
A side-by-side editorial comparison of ardlverse and biocro — release velocity, themes, recent moves, and the top alternatives to consider.
ardlverse vs biocro: 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 biocro?
BioCro swapped an unstable iteration for real root finders, changing what its crop models compute.
BioCro is a C++ crop growth simulator with an R interface, built from swappable modules for photosynthesis, respiration and development. Version 3.3.0 added multidimensional and one-dimensional root finders to the C++ source and put them to work immediately, replacing the fixed-point iteration used for intercellular CO2 with a Dekker root finder on the grounds that fixed-point iteration is known to be unstable there. Getting to that release also required moving from C++11 to C++17 and updating the bundled boost from 1.71 to 1.89.

◆ 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.
biocro
0.0ANALYTICS
BioCro swapped an unstable iteration for real root finders, changing what its crop models compute.
◆ Current state
BioCro is a C++ crop growth simulator with an R interface, built from swappable modules for photosynthesis, respiration and development. Version 3.3.0 added multidimensional and one-dimensional root finders to the C++ source and put them to work immediately, replacing the fixed-point iteration used for intercellular CO2 with a Dekker root finder on the grounds that fixed-point iteration is known to be unstable there. Getting to that release also required moving from C++11 to C++17 and updating the bundled boost from 1.71 to 1.89.
◆ Where it's heading
Two threads run together: the biology is being broken into finer interchangeable modules — separate maintenance respiration, alternative linear and logistic SLA methods, a direct development-index module — while the numerics underneath are being made solvable in general. The root finders are explicitly staged to move into the shared biocro/framework repository, so this is groundwork for other models rather than for this package alone.
◆ Prediction
More module-level alternatives that depend on simultaneous-equation solutions are the natural follow-on, and the root finders should migrate out to biocro/framework as the notes state.
