cNORM:news and change-log

This file documents the development of the package as well as open issues or points for further improvements.

Version in 3.5.4

Date: 15.05.2026 - release

This release aims at a better integration of parametric functions for the plotting functions, an overhaul of the Shiny Apps and huge performance improvements in the Taylor modelling (rankBySlidingWindows and checking for monotonicity). The subsampling will be deprecated and deleted from a future release of cNORM.

Changes:

• Set nbest to 10 in exhaustive search
• Author name order corrected in README.md
• ShinyApp streamlined
• discrete parameter when plotting betabinomial models added
• plotNorm, plotNormCurves and plotDensity fixed to correctly handle parametric models
• boost performance in rankBySlidingWindow, which as well affects performance of the parametric modelling, especially when plotting
• broader test coverage
• subsampling set to FALSE on default; the internal function is deprecated and
  will be removed in a future release
• Monotinicity with performance improvements

Version in 3.5.3

Date: 01.05.2026

Changes:

• Code review with Anthropic Claude Opus 4.7 to harden the code and to identify edge cases and handle them gracefully.
• rawTable() and normTable() now enforce monotonicity of raw and norm scores outward from the median. This reduces problems with inconsistent or NA results at the extreme ends of the model and is robust against missing values in the predicted series.
• predictRaw() is more robust for degenerate models
• predictNormByRoots() now correctly honours the force argument. When a raw score is unreachable within [minNorm, maxNorm], the function returns NA (default) or clips to the appropriate boundary (force = TRUE, now default).
• Direction-of-search is now based on the unclipped model prediction at the scale mean.
• bestModel() selection by terms or R2 is now correct under the extensive consistency screening introduced in 3.3. The chosen model now reflects the requested number of terms (or the smallest model meeting the R² threshold) rather than the row index in the filtered regsubsets summary.
• cnorm.cv(): corrected the maximum-model-size formula (k + 1) * (t + 1) - 1; pCutoff, weight handling, and norm-score SE follow Oosterhuis et al.
  2016. more faithfully and use safer indexing throughout. Fix when using sliding window ranking.
• screenSubset() cleaned up: defensive initialisation, drop = FALSE on matrix subsetting so single-row results survive, removal of dead code.
• internal function plotCumulative added for conventional norming
• removed link to CDC since server is not available anymore
• examples set to dontrun

Version in 2.0.0 (release)

Date: 2020.12.04 Version 2.0.0 features many fundamental improvements both relating to the procedure but as well to the package itself. It introduces weighted percentiles and thus helps in correcting violations of representativeness in the norm sample. There is a new main function ‘cnorm()’ that returns a cnorm object. Most functions now accept this cnorm object and do not require separate data objects and statistical models. And finally S3 methods plot(), summary() and print() have been introduced.

Changes:

• Preparing for next major release with complete redesign of S3 method structure and weighting
• New function cnorm() that does all the data preparation and modelling in one step It returns a cnorm object, which can be used in all model check, plotting and prediction functions

• Vignette revised
• All functions have been extended to accept a cnorm object instead of data and / or model
• prepareData, rankByGroup and rankBySlidingWindow no have the option to provide a weighting parameter to compensate for imbalances. The percentiles are weighted accordingly. The weighted ranking is based on an adaption of wtd.rank of the Hmisc package, provided by the courtesy of Frank Harrell

• prepareData, rankByGroup and rankBySlidingWindow can now directly handle vectors instead of a data frame, e. g. rankByGroup(raw = elfe\(raw, group = elfe\)group)
• If no group is provided and only a raw vector is present e.g. ranByGroup(raw=elfe$raw), traditional ranking of a single group is done
• Power parameter k added to prepareData
