WebStep 1: View the fit of the distribution. Use the probability plot to assess how closely your data follow each distribution. If the distribution is a good fit for the data, the points should fall closely along the fitted distribution line. Departures from the straight line indicate that the fit is unacceptable. Good fit. WebThe fitter package is a Python library for fitting probability distributions to data. It provides a simple and intuitive interface for estimating the parameters of different types of distributions, including continuous and discrete distributions. With fitter, you can easily fit a variety of distributions to your data and compare the fit of ...
