modelbpp vs popbayes: at a glance
What is modelbpp?
A structural-equation model comparison package whose feed carries links, not release notes.
modelbpp computes model-implied Bayesian posterior probabilities for structural equation models, one of several R packages from the same author covering moderation, mediation and model-comparison workflows. Its release feed is not a changelog: every entry points at the package website rather than describing what changed, so the substance of each release is not visible here. Version numbering has moved steadily from 0.1.x to 0.4.0 across roughly three years.
What is popbayes?
A wildlife population-trend package in low-maintenance mode.
popbayes fits Bayesian trends to animal population count series that mix ground counts, aerial counts and expert estimates. The visible history is short and slow: three releases across four years, with the most recent, 1.3, swapping usethis for cli in error messages and tidying the website. The substantive work in the window is 1.1, which reorganised how format_data() handles a dataset.

modelbpp
2.5ANALYTICS
A structural-equation model comparison package whose feed carries links, not release notes.
◆ Current state
modelbpp computes model-implied Bayesian posterior probabilities for structural equation models, one of several R packages from the same author covering moderation, mediation and model-comparison workflows. Its release feed is not a changelog: every entry points at the package website rather than describing what changed, so the substance of each release is not visible here. Version numbering has moved steadily from 0.1.x to 0.4.0 across roughly three years.
◆ Where it's heading
What can be read from this feed is cadence rather than content — releases clustered noticeably more tightly through 2026 than in the preceding two years, with three in five months against two in the prior eighteen. Because the entries carry no detail, any statement about what is being built would be speculation. The pattern of a stable CRAN package accelerating its release rate is the only reliable signal available.
◆ Prediction
The feed does not describe its changes, so the direction of development cannot be read from these entries; the accelerating 2026 cadence is the only thing it supports.
popbayes
0.0ANALYTICS
A wildlife population-trend package in low-maintenance mode.
◆ Current state
popbayes fits Bayesian trends to animal population count series that mix ground counts, aerial counts and expert estimates. The visible history is short and slow: three releases across four years, with the most recent, 1.3, swapping usethis for cli in error messages and tidying the website. The substantive work in the window is 1.1, which reorganised how format_data() handles a dataset.
◆ Where it's heading
Development has settled into maintenance carried largely by outside contributors, with the current release consisting of a dependency swap and message fixes from two different contributors. The one release with real design work, 1.1, moved format_data() from operating on a whole dataset to operating per count series, letting different series of the same species carry different conversion assumptions. Nothing since has changed the modelling surface.
◆ Prediction
The entries do not support a confident prediction beyond further contributor-driven maintenance; there is no visible signal of new modelling work.
