WebJan 21, 2016 · 1 Answer. The first argument to the fit () method is a sample of values from the distribution to be fit (not PDF values). So you should use the rvs () method to generate your data, not the pdf () method. Here's a simple example where I generate a sample of 250 values from the exponweib distribution, and then use fit () on that sample.
