O’zbekiston respublikasi oliy va o’rta maxsus ta’lim vazirligi samarqand iqtisodiyot va servis instituti “oliy matematika” kafedrasi ekonometrika asoslari fanidan «Vaqtli qator darajalarining avtokorrelatsiyasi»

1. Absoyut qo’shimcha o’sishni quyidagi formula bo’yicha hisoblang
Mutlaq qo’shimcha o’sish yoki kamayish- har qaysi keyingi davr darajasidan boshlang’ich yoki o’zidan oldingi davr darajasini ayirish yo’li bilan aniqlanadi.

2. Nisbiy qo’shimcha o’sishni quyidagi formula bo’yicha hisoblang
Nisbiy qo’shimcha o’sish yoki kamayish- har qaysi keyingi davr darajasidan boshlang’ich yoki o’zidan oldingi davr darajasini bo’lib, 100 ga ko’paytirish yo’li bilan aniqlanadi.
