• 1. CONTOH PERHITUNGAN ERC 1 Juni 2023
• 2. TAHAP 1: Perhitungan regresi dgn persamaan ==> CAR = b0 + b1 UE n CAR = Y UE = X y=Y-Ybar x=X-Xbar xy x 2 ERC=b1 1 3 4 -1.00 0.60 -0.60 0.36 -0.09 2 4 3 0.00 -0.40 0.00 0.16 0.22 3 5 4 1.00 0.60 0.60 0.36 0.41 4 4 3 0.00 -0.40 0.00 0.16 0.22 5 3 4 -1.00 0.60 -0.60 0.36 -0.09 6 4 3 0.00 -0.40 0.00 0.16 0.22 7 5 4 1.00 0.60 0.60 0.36 0.41 8 3 3 -1.00 -0.40 0.40 0.16 -0.12 9 5 5 1.00 1.60 1.60 2.56 0.33 10 4 1 0.00 -2.40 0.00 5.76 0.65 Total 40 34 0.00 0.00 2.00 10.4 2.18 Ybar 4 Xbar 3.4 CAR = b0 + b1 UE ==> CAR = 3.346 + 0.192 UE CAR = b0 + b1 UE ==> b1 = ERC b1 = xy / x 2 = 0.192 Y = b0 + b1 X ==> b1 = ERC b0 = Ybar - b1(Xbar) = 3.346 Y - b0 = b1X (Y- b0) / X = b1 ==> ERC pada perhitungan regresi berikutnya
