epidict vs momentuHMM

epidict vs momentuHMM: at a glance
What is epidict?
A spin-out dictionary reader for MSF epidemiological data, finding its shape on CRAN
epidict reads and applies the data dictionaries MSF field epidemiologists use to standardise outbreak and survey datasets. It was split out of the larger sitrep toolchain so the dictionary-reading and variable-renaming functions could ship on CRAN independently. Three releases in roughly two months have taken it from that initial separation to handling intersectional dictionaries.
What is momentuHMM?
The animal-movement HMM workhorse, feature-frozen since 2021 and coasting on compiler patches
momentuHMM fits hidden Markov models to animal telemetry — multiple data streams, measurement error, temporally irregular tracks, hierarchical and mixture structures. It is one of the reference implementations in movement ecology and is cited as such. Its capability set has been essentially fixed since 2021; the last four years of releases are compiler, dependency and CRAN metadata work.

A spin-out dictionary reader for MSF epidemiological data, finding its shape on CRAN
◆ Current state
epidict reads and applies the data dictionaries MSF field epidemiologists use to standardise outbreak and survey datasets. It was split out of the larger sitrep toolchain so the dictionary-reading and variable-renaming functions could ship on CRAN independently. Three releases in roughly two months have taken it from that initial separation to handling intersectional dictionaries.
◆ Where it's heading
The arc is a package being unbundled and then reassembled as its dependencies land on CRAN. The 0.1.0 release deliberately dropped msf_dict_rename_helper() because its dependencies weren't available; 0.2.0 put it back. 0.3.0 is the first release that adds rather than restores, extending intersectional dictionary support and giving callers control over name cleaning.
◆ Prediction
Expect the next releases to keep widening dictionary coverage rather than changing the API, since the reinstatement work that dominated 0.1.0 to 0.2.0 is now finished.

0.0ANALYTICS
The animal-movement HMM workhorse, feature-frozen since 2021 and coasting on compiler patches
◆ Current state
momentuHMM fits hidden Markov models to animal telemetry — multiple data streams, measurement error, temporally irregular tracks, hierarchical and mixture structures. It is one of the reference implementations in movement ecology and is cited as such. Its capability set has been essentially fixed since 2021; the last four years of releases are compiler, dependency and CRAN metadata work.
◆ Where it's heading
The development arc peaked with 1.5.0 in 2019, which brought hierarchical HMMs, discrete individual random effects and multivariate normal data streams, and effectively closed with 1.5.4 in 2021. What follows is a maintenance tail driven entirely by other people's changes: RcppArmadillo deprecating a function, Brobdingnag unexporting one, crawl dropping an import, CRAN asking for metadata edits. The package is stable in the sense that matters to its users and dormant in the sense that matters to its roadmap.
◆ Prediction
On this pattern the next release will be another upstream-forced patch rather than new modelling capability, unless a maintainer change or a new methods paper reopens development.

Frequently asked questions
What is the difference between epidict and momentuHMM?
Both compete on the same themes — r-package — within Analytics. epidict and momentuHMM are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band). See the at-a-glance table above for a side-by-side breakdown of velocity, recent sparks, and editorial themes.
Is epidict better than momentuHMM?
Sparkpulse doesn't pick a winner — we score release velocity, not feature parity. epidict and momentuHMM are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band).
