[求助]antoine方程参数拟合
 
最近写实验报告,需要拟合Antoine方程参数,懂的筒子们帮忙一下啊~~题目如下
Antoine方程:lgP=A-B/(C+T);
已知实验数据;
T=293.65 295.65 297.65 299.65 301.65 303.9;
P=5750 5940 6350 6600 6940 7300
要求拟合出参数ABC

General model:
f(x) = a-b./(c+x)
Coefficients (with 95% confidence bounds):
a = 12.95 (-337.1, 363)
b = 8065 (-6.098e+005, 6.259e+005)
c = 583.9 (-3.322e+004, 3.439e+004)

Goodness of fit:
SSE: 3.999e-005
R-square: 0.9949
Adjusted R-square: 0.9915
RMSE: 0.003651
