Xi-kvadrat taqsimoti
Xi-kvadrat (Chi Square) taqsimoti
Xi-kvadrat taqsimoti gipotezani tekshirish uchun asos sifatida ishlatiladi.
Uning ikkita parametri bor:
df — (erkinlik darajasi).
size — qaytariladigan massivning shakli.
Misol
Erkinlik darajasi 2 bo‘lgan xi-kvadrat taqsimotidan 2x3 o‘lchamli tanlanma oling:
from numpy import random
x = random.chisquare(df=2, size=(2, 3))
print(x)
