WebThis paper proposes a bootstrap goodness of fit test for the Generalized Pareto distribution (GPd) with shape parameter γ.The proposed test is an intersection–union test which tests separately the cases of γ ≥ 0 and γ < 0 and rejects if both cases are rejected. If the test does not reject, then it is known whether the shape parameter γ is either positive … WebI'm trying to fit distributions to sample data using SciPy and having good success.
