Changes in version 1.0.4                        

New features

  - Added three Abu-Shawiesh-Akyuz-Kibria (2019)
    doi:10.19139/soic.v7i2.630 population-coefficient-of-variation
    confidence intervals, ported from the companion Python package
    pycvcqv:
      - aak_adj_ci / method = "aak_adj" — adjusted-degrees-of-freedom CI
        (Eq. 21) derived from Hummel et al.'s CI for the variance; r_hat
        = 2n / (gamma_hat + 2n/(n-1)).
      - aak_ls_ci / method = "aak_ls" — large-sample CI (Eq. 26) derived
        from the log-transformed CI for the variance; A = (G_2
        + 2n/(n-1)) / n.
      - aak_als_ci / method = "aak_als" — augmented-large-sample CI
        (Eq. 32) derived from Burch's CI for the variance using a
        three-term Taylor expansion of log(S^2).
  - The three new methods are exposed both through the CoefVarCI R6
    class (as public *_ci() methods and via all_ci()) and through the
    procedural cv_versatile() function (including method = "all").
  - Internal kurtosis helpers (.g2_excess_kurtosis, .g2_bias_corrected,
    .kappa_e5, .gamma_hat_hummel) live in R/aak_helpers.R. All three CIs
    require at least 4 observations.

                 Changes in version 1.0.3 (2026-05-21)                  

Patch release addressing CRAN auto-check feedback on the 1.0.2
resubmission:

  - Wrapped author surnames in DESCRIPTION (Albatineh, Altunkaynak,
    Gamgam, Kibria, Panichkitkosolkul, Zogheib) in single quotes so
    CRAN's spell-checker no longer flags them as misspellings.
  - Removed obsolete instructions in README to download
    cvcqv_1.0.0.tar.gz from the GitHub repo (the file no longer exists;
    install from CRAN instead).

                        Changes in version 1.0.2                        

Resubmission after CRAN archival on 2022-05-19.

Bug fixes

  - Resolved the 32 checkRd: Lost braces NOTEs by rewriting
    \strong{LABEL:}{ TEXT } (an invalid two-argument form) as
    \strong{LABEL:} TEXT in CoefVarCI, CoefQuartVarCI, cv_versatile, and
    cqv_versatile documentation.
  - Removed LazyData: true from DESCRIPTION (the package ships no
    exported datasets — this was the cause of the 2022 archival).
  - Migrated all \href{http://doi.org/...} references in source comments
    and README to canonical https://doi.org/... URLs.

Continuous integration

  - Replaced legacy Travis, AppVeyor, and CircleCI configuration with
    GitHub Actions workflows derived from r-lib/actions v2: R-CMD-check,
    test-coverage, pkgdown, lint, pr-commands.
  - Added .github/dependabot.yml to keep workflow action versions
    current.

Maintenance

  - Bumped minimum R version in DESCRIPTION from 3.1.2 to 3.5.0 (current
    CRAN floor).
  - Verified the package against R 4.6.0 (2026-04-24): R CMD check
    --as-cran reports 0 errors, 0 warnings, 0 notes; all 568 testthat
    assertions pass.
