WebModeling Data and Curve Fitting¶. A 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 … WebAnd then plot our data along with the fit: Fit single gaussian curve. This fit does a pretty good job at fitting the fake gaussian data. Now that we can successfully fit a well-resolved single gaussian, peak, lets work on the more complicated case where we have several overlapping peaks which need to be convoluted from one another. bofa westchester ca
