MAQOLA ANNOTATSIYASI

Maqsad: Ushbu tadqiqot eksport hajmi (Y) va temir yo'llarda yuk aylanmasi (X) o'rtasidagi murakkab bog'liqlikni juft chiziqli regressiya modeli orqali o'rganishga qaratilgan. Maqsad temir yo'l yuk aylanmasining mamlakat eksport hajmiga miqdoriy ta'sirini aniqlash va siyosatchilar va transport va savdo sohalaridagi manfaatdor tomonlar uchun tushunchalarni taqdim etishdir. Dizayn/metodologiya/yondashuv: 2000 yildan 2022 yilgacha bo'lgan tarixiy ma'lumotlardan foydalangan holda miqdoriy tadqiqot loyihasi qo'llaniladi. Tanlangan metodologiya eng kichik kvadratlar usuli yordamida juft chiziqli regressiya modelini baholashni o'z ichiga oladi. Statistik ahamiyatlilik determinatsiya koeffitsienti, Fisherning F testi va heteroskedastiklikni tekshirish orqali tekshiriladi. Elastiklik tahlili, darajali korrelyatsiya va qoldiqlarni grafik baholash munosabatlarni har tomonlama tushunish imkonini beradi. Natijalar: Tadqiqot eksport hajmi va temir yo'l yuk aylanmasi o'rtasida kuchli va statistik jihatdan muhim ijobiy korrelyatsiyani (r = 0,92) aniqladi. Bir nechta testlar orqali tasdiqlangan regressiya modeli eksport hajmidagi o'zgaruvchanlikning 84,72% ni tushuntiradi. Iqtisodiy talqin shuni ko'rsatadiki, temir yo'l yuk aylanmasining bir birlik o'sishi eksport hajmining o'rtacha 1627720,728 donaga sezilarli o'sishiga olib keladi. Heteroskedastikaning yo'qligi modelning mustahkamligini kuchaytiradi.
