二次模型-MINITAB三天课程

二次模型 对话框处选择“Quadratic”，运行后输出结果如下 Polynomial Regression Analysis: PULL F versus ROSUN D The regression equation is PULL F = - 597.5 + 1492 ROSUN D - 919.5 ROSUN D**2 S = 0.263348 R-Sq = 92.7% R-Sq(adj) = 90.6% Analysis of Variance Source DF SS MS F P Regression 2 6.13853 3.06927 44.26 0.000 Error 7 0.48547 0.06935 Total 9 6.62400 Sequential Analysis of Variance Source DF SS F P Linear 1 5.17144 28.48 0.001 Quadratic 1 0.96709 13.94 0.007 二次项回归方程
