WebIn this tutorial, we discuss many, but certainly not all, features of scipy.stats. The intention here is to provide a user with a working knowledge of this package. We refer to the … WebAll of the statistics functions are located in the sub-package scipy.stats and a fairly complete listing of these functions can be obtained using info (stats). The list of the random variables available can also be obtained from the docstring for the stats sub-package. In the discussion below we mostly focus on continuous RVs.
