Abstract
Annotatsiya: Ushbu maqolada ekonometrik modellashtirishda muhim ahamiyatga ega bo‘lgan polinom laglar modeli, umumiy ildizlar tushunchasi, vaqt qatorlarining statsionarligi va yagona ildiz muammosi tahlil qilinadi. Tadqiqotda ushbu tushunchalarning nazariy asoslari, ularning iqtisodiy jarayonlarni tahlil qilish va prognozlashdagi o‘rni yoritilgan. Shuningdek, statsionarlikni ta’minlash usullari va yagona ildiz mavjud bo‘lganda yuzaga keladigan muammolar ko‘rib chiqilgan
