simplexgof 0.1.0

• Initial CRAN release

• Bootstrap-calibrated GoF test for simplex regression

• Paper reproduction functions included

• First release.

• simplex_fit(): maximum-likelihood fit of the simplex regression model with constant or varying dispersion (logit/log links), with C++ kernels via Rcpp.

• simplex_gof(): parametric bootstrap-calibrated goodness-of-fit test based on the aggregated local-influence statistic U_n.

• simplex_diag(): local-influence diagnostics, with a choice of analytic (bootstrap-invariant) or finite-difference gradient.

• simplex_Un_asymptotic(): asymptotic version of the statistic for the null-distribution study.

• Plotting: plot_influence(), plot_envelope() (bootstrap envelope), plot_gof_boot(), plus plot() methods for the fitted and test objects.

• Reproduction helpers: paper_ammonia(), paper_pbsc(), paper_fig1(), and standalone scripts in inst/scripts/.

• Two bundled datasets: ammonia (n = 21) and pbsc (n = 239).
