WebA common use of least-squares minimization is curve fitting, where one has a parametrized model function meant to explain some phenomena and wants to adjust the numerical values for the model so that it most closely matches some data. With scipy, such problems are typically solved with scipy.optimize.curve_fit, which is a wrapper around scipy ... WebA mean is a good measure if you’re sure that the data is normally distributed (i.e. it follows the classic bell curve shape). Otherwise, the median is your next best measure for a quick analysis. However, I prefer to distribution fit and find the x-position of the peak of the distribution! How do you do this? Easy!
