Multiple Linear Regression Ppt. Multiple Linear Regression Equation • Sometimes also called multivariate linear regression for MLR • The prediction equation is Y′= a + b 1X 1 + b 2X 2 + b 3X 3 + ∙∙∙b kX k • There is still one intercept constant a but each independent variable (eg X 1 X 2 X 3) has their own regression coefficient File Size 695KBPage Count 52.
