Overview

About

Provides some easy-to-use functions and classes to calculate variability measures such as coefficient of variation with confidence intervals provided with all available methods. References are 'Panichkitkosolkul' (2013) doi:10.1155/2013/324940, 'Altunkaynak' & 'Gamgam' (2018) doi:10.1080/03610918.2018.1435800, 'Albatineh', 'Kibria', Wilcox & 'Zogheib' (2014) doi:10.1080/02664763.2013.847405.

Changes in 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.
