Multiple Regression FormulaStep 1: Calculate X12, X22, X1y, X2y and X1X2. Step 2: Calculate Regression Sums. Next, make the following regression sum calculations: Σ x12 = Σ X12 – (ΣX1)2 / n = 38,767 – (555)2 / 8 = 263.875. Σ x22 = Σ X22 – (ΣX2)2 / n = 2,823 – (145)2 / 8 = 194.875. Σ x1y = Σ X1y – (ΣX1Σy) / n = 101,895 – (555*1,452) / 8 = 1,162.5.
