我做了个正态分布的拟合,好像也叫高斯分布、
结果如下:
General model Gauss1:
f(x) = a1*exp(-((x-b1)/c1)^2)
Coefficients (with 95% confidence bounds):
a1 = 0.1437 (0.136, 0.1513)
b1 = 0.02975 (-0.001149, 0.06065)
c1 = 0.7099 (0.6662, 0.7536)
Goodness of fit:
SSE: 0.001703
R-square: 0.9758
Adjusted R-square: 0.9745
RMSE: 0.006526
但是我根据A1和C1算出的方差为什么是不一样的?到底期望和方差是多少啊
还有这么拟合T分布啊、
