stdmod vs tulpaObs: at a glance
What is stdmod?
A moderation-analysis package now pointing users at its own siblings for the harder work.
stdmod computes standardized moderation effects in regression, part of a cluster of R packages from the same author covering moderation, mediation and model comparison. Its release feed is a CRAN-announcement format — several entries carry nothing but a version and a link — and its development has slowed markedly, with the substantive feature work sitting back in 2024. The most recent release is documentation rather than code.
What is tulpaObs?
An occupancy-modeling package that just deleted its own duplicate vocabulary for diagnostics.
tulpaObs is the ecological occupancy and abundance modeling layer built on the tulpa engine, releasing at high frequency and with version numbers that do not advance monotonically in publication order. The current window covers three strands: a breaking consolidation of its diagnostic surface onto generics the engine now owns, the completion of simulation-based-calibration registration across all 27 model families, and a correctness fix that materially moves previously reported information criteria. Several releases exist only to pin a new engine version and record what that change does when measured from this side.

stdmod
2.5ANALYTICS
A moderation-analysis package now pointing users at its own siblings for the harder work.
◆ Current state
stdmod computes standardized moderation effects in regression, part of a cluster of R packages from the same author covering moderation, mediation and model comparison. Its release feed is a CRAN-announcement format — several entries carry nothing but a version and a link — and its development has slowed markedly, with the substantive feature work sitting back in 2024. The most recent release is documentation rather than code.
◆ Where it's heading
The clearest signal is the latest release redirecting users toward betaselectr and manymome for tasks stdmod also covers, on the grounds that those packages handle them more comprehensively. That is a package consciously narrowing its scope within a family rather than competing with its siblings. The earlier feature work — conditional effects at chosen moderator values, R-squared increase reporting, print formatting — reads as a stable core that has since been left alone.
◆ Prediction
Expect stdmod to stay in maintenance while the author's newer packages absorb the overlapping functionality, with future releases likely limited to CRAN compliance and documentation.
tulpaObs
6.3ANALYTICS
An occupancy-modeling package that just deleted its own duplicate vocabulary for diagnostics.
◆ Current state
tulpaObs is the ecological occupancy and abundance modeling layer built on the tulpa engine, releasing at high frequency and with version numbers that do not advance monotonically in publication order. The current window covers three strands: a breaking consolidation of its diagnostic surface onto generics the engine now owns, the completion of simulation-based-calibration registration across all 27 model families, and a correctness fix that materially moves previously reported information criteria. Several releases exist only to pin a new engine version and record what that change does when measured from this side.
◆ Where it's heading
The package is systematically removing the parallel names it had accumulated for concepts owned elsewhere, and the registration work is closing rather than expanding — the SBC scope reached its final family in this window. Its cadence is tightly coupled to the engine's, to the point where the interesting content of some releases is a dependency floor plus a measurement. With the breaking rename and the registration scope both behind it, the surface work looks close to finished.
◆ Prediction
Expect the follow-on releases to be consolidation rather than expansion — registry branches, regenerated documentation, engine pins — with the next substantive move most likely a new model family beyond the original registration scope.
