What is edina?

A finished psychometric estimator kept alive by toolchain upkeep, not new modeling work.

edina is a single-purpose Rcpp/Armadillo implementation of the Exploratory DINA model, feature-complete since its 2020 debut. Its entire visible surface — estimation plus Q-matrix comparison across k values — has not changed in five years. The only 2025 activity is a maintenance release that raises the R, Rcpp and RcppArmadillo floors so the package still compiles.

What is mcmcensemble?

An ensemble sampler just admitted its walkers were barely talking to each other.

mcmcensemble provides affine-invariant ensemble MCMC samplers — differential evolution and stretch move — behind a single MCMCEnsemble() entry point. The API consolidated in 3.0.0 around a flexible inits argument and a hidden internal surface, with parallelism delegated to the future framework. The 2025 release fixed a defect in the sampling behaviour itself, and results now differ from every earlier version.

A finished psychometric estimator kept alive by toolchain upkeep, not new modeling work.

◆ Current state

edina is a single-purpose Rcpp/Armadillo implementation of the Exploratory DINA model, feature-complete since its 2020 debut. Its entire visible surface — estimation plus Q-matrix comparison across k values — has not changed in five years. The only 2025 activity is a maintenance release that raises the R, Rcpp and RcppArmadillo floors so the package still compiles.

◆ Where it's heading

The gap between 0.1.1 and 0.1.2 is over five years, and 0.1.2 contains no modeling changes at all: dependency floors, a Makevars cleanup for newer Armadillo, a Quarto README, a CITATION fix for CRAN notes, and refreshed CI. This is custodial maintenance of a research artifact rather than active development. The same release landed across the maintainer's other packages the same morning — rrum got a near-identical body ten minutes earlier — which marks it as a lab-wide compatibility sweep, not an edina-specific push.

◆ Prediction

Expect the next release to be another compatibility bump triggered by an Armadillo or Rcpp change rather than new estimation features, on a similar multi-year cadence.

An ensemble sampler just admitted its walkers were barely talking to each other.

◆ Current state

mcmcensemble provides affine-invariant ensemble MCMC samplers — differential evolution and stretch move — behind a single MCMCEnsemble() entry point. The API consolidated in 3.0.0 around a flexible inits argument and a hidden internal surface, with parallelism delegated to the future framework. The 2025 release fixed a defect in the sampling behaviour itself, and results now differ from every earlier version.

◆ Where it's heading

Development has moved from packaging to statistics. The early releases were about shape: a rename, argument alignment, moving coda to Suggests, adding tests, then parallel execution and named-vector support. The 3.0.0 release closed the API down to one wrapper and generalised initialisation. What is left, as 3.2.0 shows, is the correctness of the sampler itself — walker correlation, ergodicity checks, and grid artefacts in the differential evolution step were all addressed in a single release, all reported by one contributor. The package is being audited rather than extended.

◆ Prediction

Further sampler-behaviour fixes are the most likely next move, since three separate correctness issues surfaced together in the last release and the package's API has been stable since 3.0.0.
