Tugas Regresi Nonparametrik (Regresi Polinomial dengan R: Penerapan dan Pemilihan Derajat Optimal via Cross-Validation)
Analisis regresi polinomial pada data simulasi kuadratik (n=100). Tiga model (linier, derajat 2, derajat 3) dibandingkan dengan ANOVA, AIC, dan RMSE. Pemilihan derajat optimal menggunakan 10-fold cross-validation (5 ulangan) menghasilkan derajat 2 dengan RMSE terkecil (1.825) dan R² = 0.788. Model final: ŷ = 5.34 + 1.80x – 0.275x², semua koefisien signifikan. Kesimpulan: derajat 2 adalah model terbaik dan paling parsimonis.
