बहु सहसंबंध गुणांक के लिए सामान्य सूत्र
\(\rm R^2_1{.}{_2}{_3} = \frac{r_{12}^{2}+r_{13}^{2}-2r_{12}r_{13}r_{23}}{1-r_{23}^{2}}\)
एक बहु सहसंबंध गुणांक एक गैर-ऋणात्मक गुणांक होता है।
यह 0 और 1 के बीच का मान है। यह ऋणात्मक मान नहीं मान सकता है।
यदि X2 और X3 पर X1 का बहु सहसंबंध गुणांक शून्य है, तब:
यदि R1.23 = 0 है तब r12 = 0 और r13 = 0
R1.23, R1.32 के समान है।
