Curve fit for 6mM Lactose

Gauss 2 to 4


Gauss 4

General model Gauss4:

      f(x) = 
a1*exp(-((x-b1)/c1)^2) + a2*exp(-((x-b2)/c2)^2) +
a3*exp(-((x-b3)/c3)^2) + a4*exp(-((x-b4)/c4)^2)

Coefficients (with 95% confidence bounds):

      a1 =      -139.1  (-351.8, 73.56)
b1 = 3666 (3482, 3851)
c1 = 309.1 (173.9, 444.2)
a2 = -211.6 (-1297, 873.6)
b2 = 3953 (3560, 4345)
c2 = 220.6 (-71.35, 512.6)
a3 = 473 (-204.4, 1150)
b3 = 813.4 (-8312, 9939)
c3 = 3875 (-1.494e+004, 2.269e+004)
a4 = 4.508e+015 (-5.202e+019, 5.203e+019)
b4 = 4.806e+004 (-1.73e+007, 1.74e+007)
c4 = 8138 (-1.595e+006, 1.611e+006)


Goodness of fit:

 SSE: 325.2
R-square: 0.9982
Adjusted R-square: 0.9979
RMSE: 2.272
