WebI have a data set and a kernel density estimate for those data. I believe the KDE should be reasonably well described by an exponentinally modified Gaussian, so I'm trying to sample from the KDE and fit those samples with a function of that type. However, when I try to fit using scipy.optimize.curve_fit, my fit doesn't match the data well at all.
