Formilaaji regresiyoŋ

Ɗii ko kurbuuji jeegom ɗi hiisirde ndee waawi hiisde: liineer, $\displaystyle y = a + bx$; eksponansiyel, $\displaystyle y = a e^{bx}$; logaritmik, $\displaystyle y = a + b \ln x$; doole, $\displaystyle y = a x^{b}$; inwers, $\displaystyle y = a + \frac{b}{x}$; e kwadratik, $\displaystyle y = a + bx + cx^{2}$. Juumre ina waɗa so jaabawol yettiima $\displaystyle 10^{100}$, so les feccere ko 0, so ɗaɗol kaare limre negatif ina ɗaɓɓaa, walla so regresiyoŋ kwadratik alaa jaabawol.
