NEWS file for the free1way.docreg package

Changes in Version 1.1-0 (2026-10-29)

Bugfixes

• confint(<free1way>, parm) returned confidence intervals for all parameters when parm requested a subset.

• confint(<free1way>, what = "OVL") now includes one for shift effect confidence intervals including zero.

Documentation

• Add new Wilcoxon package vignette.

Features

• free1way(, MPL_Jeffreys = TRUE) implements maximum penalised likelihood estimation with Jeffreys prior for all model parameters simultaneously, along with Wald-type inference.

• Added experimental scale.test function for testing scale parameters. Parameter estimation, however, is not available because the corresponding optimisation problem is non-convex.

Other

• Log-likelihood contributions are computed directly on the log-scale in a more stable way.

• summary(<free1way>) renamed p-values to Pr() and thus printCoefmat recognises them.

• rfree1way also accepts offset terms equal to the number of simulated observations, allowing to sample from more complex models.

Changes in Version 1.0-3 (2026-09-07)

Documentation

• Prepare for upcoming changes in penalisation implementation: free1way will perform penalisation only when requested.

Changes in Version 1.0-2 (2026-06-30)

Bugfixes

• Fix missing links in vignette.

Changes in Version 1.0-1 (2026-06-16)

Bugfixes

• strat_ratio != 1 in rfree1way didn't work as advertised.

• Zeros in prob argument to power.free1way.test triggered an error and are now handled correctly.

Changes in Version 1.0-0 (2026-05-18)

• Function free1way implementing semiparametrically efficient inference procedures (likelihood- and permutation-based) in distribution-free stratified K-sample oneway layouts was added to the stats package. Approximate (via power.free1way.test) and simulation-based (utilising rfree1way for random number generation) power-assessment and sample-size planning as well as model diagnostics (available from a plot method and probability-probability plots in ppplot) complement the functionality. Package free1way.docreg provides additional documentation and regression tests.
