eratosthenes vs ordbetareg: at a glance
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 ordbetareg?
A brms wrapper for bounded outcomes that keeps handing users more control over the model's internals.
ordbetareg fits ordered beta regression — outcomes bounded at both ends, with mass at the bounds — on top of brms. Each release has opened up a layer that was previously fixed: v0.5.0 added posterior predictive checks and user-specified bounds, and v0.8 added a full prior override that makes cutpoint modeling possible, plus component-wise prediction of the bottom, middle and top of the scale.

◆ 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.
ordbetareg
0.0INFRA · APIS
A brms wrapper for bounded outcomes that keeps handing users more control over the model's internals.
◆ Current state
ordbetareg fits ordered beta regression — outcomes bounded at both ends, with mass at the bounds — on top of brms. Each release has opened up a layer that was previously fixed: v0.5.0 added posterior predictive checks and user-specified bounds, and v0.8 added a full prior override that makes cutpoint modeling possible, plus component-wise prediction of the bottom, middle and top of the scale.
◆ Where it's heading
The direction is from a convenience wrapper toward something users can take apart. The pattern across releases is the same move repeated at greater depth: what was hard-coded becomes an argument. Documentation is expanding in step, with the vignette now covering power analysis and cutpoint modeling, which suggests the audience is being taught to use the lower-level controls rather than the defaults.
◆ Prediction
Given that priors, bounds and predicted components are now all exposed, the next release most plausibly extends the diagnostic and plotting surface rather than the model itself — though releases here are more than a year apart, so timing is unpredictable.
