Relyence Weibull supports several distribution types for performing your analysis. The goal of Weibull analysis is to evaluate your life data and find a distribution, or failure curve profile, that best fits your data. If you prefer to use a particular distribution for your analyses, you may set the distribution directly. Relyence Weibull supports several distribution types for performing your analysis.

You want to fix the loc and the first shape parameter (a), this is done with floc=0,f0=1. Fitting will then give you params c and scale, where c corresponds to the shape parameter of the two-parameter Weibull distribution (often used in wind data analysis) and scale corresponds to its scale factor. so i been doing a lot of python challenges and i realized that list, tuples, and dictionaries are like the backbone of programming. its like a line is just a line but when you add 3 more lines you can actually make something out of it like a square. wtf my mind is blown. also the python standard library is amazing cause people actually wrote ... 1.1 The Two-Parameter Weibull Distribution There are many applications for the Weibull distribution in statistics.
