randomwalk
randomwalk spent every release getting an R simulation to run in the browser, not on a server.
A side-by-side editorial comparison of gdverse and simStateSpace — release velocity, themes, recent moves, and the top alternatives to consider.
gdverse is turning geographical detector methods into inference, not just point estimates.
A geographical detector toolkit for spatial stratified heterogeneity, shipping small numbered releases every few months. Recent work centres on statistical rigour: confidence intervals for the q-statistic (experimental in 1.3-2, made more robust in 1.6), reported significance for interaction detection, and a fix for stratification collision in that same interaction path. The rest is Python-interop maintenance — reticulate compatibility, parallel stability in cpd_disc, and dependency configuration.
State-space data simulation for R, filled in one function at a time
simStateSpace generates data from state-space models — discrete-time SSM and VAR, continuous-time linear SDE and Ornstein-Uhlenbeck — for use in simulation studies of longitudinal and intensive repeated-measures designs. Recent releases add moment and intercept helpers rather than new model families: SimMVN(), the LinSDE intercept functions, and consolidation of the four separate parameter-simulation functions into one. Release notes are terse, marked Patch, and typically name one or two functions.

The arc is from computing detector statistics to qualifying them. Confidence intervals, significance reporting and non-centrality parameter estimation are all about telling users how much to trust a q-value, which is the gap between a research script and a package other people cite. The Python-dependency work is the recurring tax on that: several releases exist mainly to keep reticulate-backed models passing checks.
Expect the experimental q-statistic confidence intervals to be promoted to a stable, documented interface across the detector family, since the last two releases have both worked on their robustness and reporting.

Release notes are terse, marked Patch, and typically name one or two functions.
The package is being filled in methodically toward completeness across its four model families — whatever exists for the SSM side eventually appears for LinSDE and back again, as SSMInterceptEta/SSMInterceptY in 1.2.15 were followed by their LinSDE counterparts in 1.2.16. The other visible move was outward: bootstrap components were split into a separate bootStateSpace package, keeping this one to simulation alone. It sits in the same author's cluster of state-space and mediation packages, whose published methods papers the releases cite.
Expect the pattern to continue — small patch releases adding the missing counterpart function for a model family already served, with any larger capability likely spun out into its own package as bootstrapping was.
