What is posteriordb?

A reference posterior database that hit 1.0 with a paper, and is now graded on the statistics it ships.

posteriordb distributes Bayesian models with data and reference posterior draws so inference algorithms can be benchmarked against a common target. It reached 1.0.0 alongside a published paper, and ships both R and Python access. Recent work is about the metadata around the draws — licences, machine-readable dataset descriptors, and additional summary statistics.

What is USAboundaries?

Seven years dormant, then two releases dragging every census boundary from 2020 to 2024

USAboundaries supplies contemporary and historical US boundary data — states, counties, congressional districts, cities, ZIP code tabulation areas — as sf objects, with the bulk data held in a companion USAboundariesData package. After a gap running from 2018 to late 2025, two releases a month apart refreshed the contemporary census vintage from 2020 to 2024: 0.5.0 covered everything except states, and 0.5.1 finished the job.

0.0

A reference posterior database that hit 1.0 with a paper, and is now graded on the statistics it ships.

◆ Current state

posteriordb distributes Bayesian models with data and reference posterior draws so inference algorithms can be benchmarked against a common target. It reached 1.0.0 alongside a published paper, and ships both R and Python access. Recent work is about the metadata around the draws — licences, machine-readable dataset descriptors, and additional summary statistics.

◆ Where it's heading

The database is maturing from a model collection into a citable benchmark asset: licence information per model, a Croissant metadata file for dataset discovery, and summary statistics like mean squared value and lag-1 autocorrelation that let users judge whether reference draws are good enough for their comparison. Earlier releases were about content and correctness; current ones are about making the content machine-readable and verifiable.

◆ Prediction

Further work should continue on draw-quality diagnostics and metadata rather than model count, since the last two releases both added ways to assess the reference draws instead of adding posteriors.

Seven years dormant, then two releases dragging every census boundary from 2020 to 2024

◆ Current state

USAboundaries supplies contemporary and historical US boundary data — states, counties, congressional districts, cities, ZIP code tabulation areas — as sf objects, with the bulk data held in a companion USAboundariesData package. After a gap running from 2018 to late 2025, two releases a month apart refreshed the contemporary census vintage from 2020 to 2024: 0.5.0 covered everything except states, and 0.5.1 finished the job.

◆ Where it's heading

For a data package the release cycle is the data vintage, and the 0.3.0 split into a separate data package was designed precisely so those refreshes would not require a code release. That the 2024 update still arrived as two package versions seven years later says the mechanism is being used sparingly. Nothing in the feed shows work on the API itself since us_cities() gained an sf return type and a states argument in 2018.

◆ Prediction

The next release is most likely another vintage refresh when the census data moves again, rather than new geographies or functions. The split of 0.5.0 and 0.5.1 suggests state boundaries are handled on a separate path from the rest and may lag again.
