cvcqv 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.

cvcqv 1.0.3

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).

cvcqv 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.
