1、利用cftool曲线拟合工具箱:Linear model Poly2: f(x) = p1*x^2 + p2*x + p3Coefficients (with 95% confidence bounds): p1 = -0.03816 (-0.05458, -0.02173) p2 = 13.56 (12.62, 14.51) p3 = -1.28 (-8.511, 5.952)Goodness of fit: SSE: 248 R-square: 0.9993 Adjusted R-square: 0.9992 RMSE: 5.952注:1.误差平方和(SSE) 2. R-Square(复相关系数或复测定系数) 3. Adjusted R-Square(调整自由度复相关系数) 4.Root mearn squared error(RMSE),(均方根误差)。
