lifecontingencies vs ordbetareg: at a glance
What is lifecontingencies?
An actuarial mainstay spends its releases on CI plumbing, not on new mathematics.
lifecontingencies is a long-running R package for actuarial life-contingency mathematics. Its three most recent tags show a maintainer keeping the infrastructure alive rather than extending the library: 1.5.2 is entirely author-metadata corrections, CI workflow repairs and release automation, 1.4.4 moved presentValue() onto Rcpp, and 1.4.1 states outright that it is identical to the version before it. The 1.5.2 notes jump from 1.4.4, so whatever happened in between never reached this feed.
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
lifecontingencies is a long-running R package for actuarial life-contingency mathematics. Its three most recent tags show a maintainer keeping the infrastructure alive rather than extending the library: 1.5.2 is entirely author-metadata corrections, CI workflow repairs and release automation, 1.4.4 moved presentValue() onto Rcpp, and 1.4.1 states outright that it is identical to the version before it. The 1.5.2 notes jump from 1.4.4, so whatever happened in between never reached this feed.
◆ Where it's heading
The one genuine engineering thread is performance: rewriting presentValue() in Rcpp targets the innermost loop of every annuity and insurance valuation the package performs. Everything since has been about keeping CRAN checks green across platforms — TinyTeX install order, cross-platform caching, automated release tagging — plus a set of Italian actuarial benchmark tests that pin results against published tables. That is maintenance discipline on a stable API, not expansion.
◆ Prediction
Expect further patch tags carrying CI and documentation work, with any Rcpp performance work extending from presentValue() into adjacent valuation functions if it continues at all.
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.
