Rather than relying on ACF/PACF plots or\nstepwise search (as in auto.arima), the package exhaustively\nevaluates every ARIMA(p,d,q) triple in P x D x Q, ranks all\nconverged models by AIC, AICc, BIC, and HQIC simultaneously,\ncomputes Akaike weights for model uncertainty quantification,\nproduces ensemble forecasts, and provides publication-quality\ndiagnostic plots. The algorithm is flexible, transparent, and\nwidely applicable for quick, reproducible ARIMA model\nselection.
