ProUCL.Crit.Vals.for.AD.Test.for.Gamma.array {EnvStats}

ProUCL Critical Values for Anderson-Darling Goodness-of-Fit Test for Gamma Distribution

Description

Critical Values for the Anderson-Darling Goodness-of-Fit Test for a Gamma Distribution, as presented in Tables A-1, A-3, and A-5 on pages 283, 285, and 287, respectively, of USEPA (2015).

Usage

data("ProUCL.Crit.Vals.for.AD.Test.for.Gamma.array")

Format

An array of dimensions 32 by 11 by 3, with the first dimension indicating the sample size (between 5 and 1000), the second dimension indicating the value of the maximum likelihood estimate of the shape parameter (between 0.025 and 50), and the third dimension indicating the assumed significance level (0.01, 0.05, and 0.10).

Details

See USEPA (2015, pp.281-282) and the help file for gofTest for more information. The data in this array are used when the function gofTest is called with test="proucl.ad.gamma". The letter k is used to indicate the value of the estimated shape parameter.
