The amplitude is based on the difference between Ymax and Yinf; the two exponentials are set to be <0; I didn't try to get fancy and figure out heuristics for the second exponential but just took a rough clue from the original solution; if you didn't have that, it might take some more work to get a … WebOct 17, 2024 · fittype ('exp1') ans = General model Exp1: ans (a,b,x) = a*exp (b*x) Now, you want that curve to pass through the point y0 = a*exp (b*x0) So you can reduce the model by one parameter, using the above information. That is, a = y0/exp (b*x0) Therefore, your model is now: y = yo/exp (b*x0) * exp (b*x)

For example, if you have a vector of scores, x, from the distribution to be fit, you can get a maximum-likelihood fit with: mydist = ChiSq (round (mean (x)); % A good starting value. mydist.EstML (x) % Will adjust V up or down to improve max-likelihood fit.
