Changes in version 0.1.0 (2026-06-19) - 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).
