Hi,
I would like to fit a data set which looks like two cumulative Gaussian distributions plus a straight line.
f(x)= c1*[F(x,0,SD1 - 0.5]+c2*F(x,mean2,SD2)+c3*z
where F(x;mean,SD) denotes the cumulative function of a Gaussian
with means and SDs.
Now I want the parameters c1, c2, c3, SD1, SD2, and mean2 of the fitting function to be determined by by minimization of a weighted least-squares index.
Does anybody have an indea how to proceed?
Alex

One should be able to do this with the Peak Fitting Module ... |
