help needed to fit dataset with two peaks
(OP)
I have a distribution with two peaks where the right hand one resemble Gaussian distribution. I want to fit a curve to the entire dataset, determine the minimum point between two peaks, cut data set using that figure, and try to fit some parametric distribution to both sets of data.
I managed to get very good non-parametric fit for the entire dataset (using dfittool) but cannot get its function (to be able to determine MIN). I tried to fit various polynomials but they do not produce good fit. Can anyone advise me how to get a function from the non-parametric fit?

RE: help needed to fit dataset with two peaks
Seems to me, the way to do this is to directly fit to two parametric distributions.
