QuadratiK 1.1.3 (Development version)

NEW FEATURES

• the function rpkb() returns directly the generated data set and not a list.
• change repository name from QuadratiK-package to QuadratiK.

MINOR IMPROVEMENTS

• packages ggplot2 and foreach not called as full packages but using importFrom.
• nClust argument of pkbc function has no default value.
• usage of standardGeneric (see https://adv-r.hadley.nz/s4.html#s4-generics).

BUG FIXES

• goodpractice suggestions.
• specify that rho in pk.test() cannot be equal 1.
• styling and spelling errors.

DOCUMENTATION FIXES

• Uniform notation: d is dimension in Eucldean space with spherical data lying on the (d-1)-dimensional sphere
• Specify dimension of input matrix x in clustering functions.
• Improve explanation of Average Silhouette Width.
• Better explanation of motivation for L2 normalization in the wireless data set application.

QuadratiK 1.1.2 (2024-10-29)

NEW FEATURES

• Added NEWS.md file.

• More detailed information in the README file and documentation (the methods are more usable and clearer for a broader audience).

MINOR IMPROVEMENTS

• Added badges for rOpenSci review status, test coverage, R CMD CHECK, CRAN downloads.
• Addition of test codes with testthat package.
• In particular, testing that random sampling from the PKBD and the wrapped Cauchy distribution is equivalent.

BUG FIXES

• scatter-plots related to the clustering algorithm results.
• computation of evaluation measures (pkdc_validation function) when the true labels are not provided.

DOCUMENTATION FIXES

• The help documentation for the methods defined for the classes in the package can be accessed directly (addition of roxygen tag name and aliases).

QuadratiK 1.1.1 (2024-06-05)

NEW FEATURES

• Improve computation of variance for k-sample test
• Add breast_cancer and wine data sets

MINOR IMPROVEMENTS

• print() and summary() methods of the kb.test object for the two and k-sample tests

BUG FIXES

• Computation of test statistics for normality test

DOCUMENTATION FIXES

• Correction of typos

QuadratiK 1.1.0 (2024-05-14)

NEW FEATURES

• Add GitHub links to the DESCRIPTION file
• Add unit tests
  
• Add CONTRIBUTING.md
• Add srr standards for the categories: General, Clustering and Probability Distributions
• Add methods for the clustering object pkbc: show(), summary(), estract_stats(), plot() and predict()
• Add vignette generate_rpkb.Rmd
• Add CODE_OF_CONDUCT.md
• Create the GitHub page using pkgdown
• Add V-statistic for Normality test, with corresponding Critical Value and Degrees of Freedom with the function DOF_norm()
• Update kb.test S4 class slots, kb.test() function, unit-test codes, summary() and print() method for including the V-statistic
• Add Trace statistic for two and k-sample tests
• Add computation of the Variance for two and k-sample tests

MINOR IMPROVEMENTS

• Addition of GitHub workflows for R-CMD-check, test-coverage and pkgcheck
• Update codes to check arguments of function pk.test()
• Update codes to check arguments of function kb.test() and select_h()
• Modify indentation and assignments (using ‘<-’) following goodpractice standards
• Update references in README.md file

BUG FIXES

• Add codemeta.json to .Rbuildignore

• Add CONTRIBUTING.md to .Rbuildignore

• Fix warning from internal function compare_qq()

• Add doc folder to .gitignore

• Modify returned test statistics multiplying them by the sample size

• Remove “Nonparam” centering option for the Normality test

• Critical value of the V-statistic divided by the variance in the function pk.test()

DEPRECATED AND DEFUNCT

• summary_stat() and validation() substituted by estract_stats() and pkbc_validation()

DOCUMENTATION FIXES

• C++ functions are set as internal functions
• Correction of typos
• Remove Date from DESCRIPTION
• Update References in the DESCRIPTION file
