title: Calculating the centroids of two superposed gaussian functions
body: <p>I am trying to find a solution to the following problem. I have a set of points which should model a sum of 2 Gaussian functions centered at different points. I need to find these two points. Up to now my approach has been to find the centroid of the whole set and cut the set of date below and above it. Then I calculate the centroid of each piece and those are my centers. This approach however cuts the information of, say, the left Gaussian which leaks into the right half of the data. This makes the procedure fail when the Gaussians are close together. Is there way to do this more intelligently? Due to the computational difficulty I would prefer if the solution didn't involve curve fitting.</p>
