Description: Implements the bootstrap-calibrated local-influence
        goodness-of-fit test for simplex regression models with
        constant or varying dispersion, following the local influence
        approach of Zhu and Zhang (2004) <doi:10.1093/biomet/91.3.579>
        and the simplex regression model of Barndorff-Nielsen and
        Jorgensen (1991) <doi:10.1016/0047-259X(91)90008-P>. The test
        statistic aggregates individual local-influence measures under
        case-weight perturbation. Because the first-order asymptotic
        normal calibration is severely liberal in finite samples, a
        parametric bootstrap calibration is provided that restores
        accurate size control and delivers high power against omitted
        covariates, neglected dispersion, and distributional
        misspecification. Plotting functions reproduce the figures and
        tables of the companion methodological paper. Computational
        kernels are implemented in 'C++' via 'Rcpp' and 'RcppArmadillo'
        for speed, and two real datasets are bundled.
