What is eratosthenes?

eratosthenes spends 0.1.0 hardening inputs rather than adding chronology methods.

eratosthenes does Bayesian estimation of archaeological chronologies from relative sequences, absolute constraints and artifact assemblages. The 0.0.9 line built out the inference diagnostics — traceplots, histograms, batch-means MCSE reporting, displacement estimation — and then consolidated artifact probability-density estimation into a single gibbs_ad_type(). The 0.1.0 tag turns outward instead, adding validators for every user-supplied structure and replacing seq_check() with a more informative seq_diag().

What is geocomplexity?

A spatial complexity package that shipped its method, then went quiet

geocomplexity computes geographical complexity from spatial dependence and configuration similarity across both vector and raster data, and uses it to build spatial weight matrices and a complexity-aware geographically weighted regression. That capability arrived complete in the 0.1.0 release of September 2024. The three releases since contain no functional change: a citation file, a dependency trim, one function moved out to a sibling package, and a maintainer surname correction.

eratosthenes spends 0.1.0 hardening inputs rather than adding chronology methods.

◆ Current state

eratosthenes does Bayesian estimation of archaeological chronologies from relative sequences, absolute constraints and artifact assemblages. The 0.0.9 line built out the inference diagnostics — traceplots, histograms, batch-means MCSE reporting, displacement estimation — and then consolidated artifact probability-density estimation into a single gibbs_ad_type(). The 0.1.0 tag turns outward instead, adding validators for every user-supplied structure and replacing seq_check() with a more informative seq_diag().

◆ Where it's heading

The package is moving from research code to something a non-author can run. Consolidating estimation behind one function, then wrapping every input class in a validator, are the two steps that make failures legible instead of cryptic, and the diagnostics added earlier serve the same end for the sampler itself. Nothing in the window changes the underlying model; the work is all about making it usable and its output checkable.

◆ Prediction

With inputs validated and diagnostics in place, the next release is more likely to extend the constraint or assemblage modelling than to keep reworking the interface, though the feed's three sparse tags give little to read a cadence from.

A spatial complexity package that shipped its method, then went quiet

◆ Current state

geocomplexity computes geographical complexity from spatial dependence and configuration similarity across both vector and raster data, and uses it to build spatial weight matrices and a complexity-aware geographically weighted regression. That capability arrived complete in the 0.1.0 release of September 2024. The three releases since contain no functional change: a citation file, a dependency trim, one function moved out to a sibling package, and a maintainer surname correction.

◆ Where it's heading

The package sits inside Wenbo Lyu's spatial statistics family, where shared functionality migrates into the common sdsfun package rather than being duplicated across dependents. moran_test left geocomplexity for sdsfun in 0.2.0, which is the same consolidation pattern visible across the author's other packages. What remains here is the method-specific surface, and it has not changed in eighteen months.

◆ Prediction

The entries give no signal of planned functional work; on this pattern the next release is as likely to be metadata or another function migration to sdsfun as anything user-visible.
