Webdistfit is a python package for probability density fitting of univariate distributions for random variables. With the random variable as an input, distfit can find the best fit for parametric, non-parametric, and discrete distributions. For the parametric approach, the distfit library can determine the best fit across 89 theoretical distributions. WebJul 10, 2016 · 6. There is no distribution called weibull in scipy. There are weibull_min, weibull_max and exponweib. weibull_min is the one that matches the wikipedia article on the Weibull distribuition. weibull_min has three parameters: c (shape), loc (location) and scale (scale). c and scale correspond to k and λ in the wikipedia article, respectively.
