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.
