Penimbang Skor Kecenderungan Diperkasakan Pembelajaran Mesin

Penimbang skor kecenderungan diperkasakan pembelajaran mesin (ML-PSW) menggantikan regresi logistik dengan algoritma ML yang fleksibel — seperti peningkatan kecerunan (gradient boosting), LASSO, atau hutan rawak (random forests) — untuk menganggarkan skor kecenderungan, kemudian menggunakan pemberat songsangan kebarangkalian (inverse probability weights) untuk mengimbangi kumpulan rawatan dan kawalan. Ini mengurangkan bias salah spesifikasi model apabila hubungan sebenar antara kovariat dan penugasan rawatan adalah kompleks atau berdimensi tinggi.
