For instance: Mathematical functions with automatic domain, Original Source of the Generator and BitGenerators, Performance on different Operating Systems. If ratio is between 0.01 and 0.99, numpy.random.permutation is used. I can't think of any reason why I should use a wrong algorithm here just because it is probably "random enough", when using the right algorithm has no disadvantage whatsoever. However, this may not be the most efficient method if length of array is large but no. thanks a lot. instantiate it directly and pass it to Generator: The Box-Muller method used to produce NumPys normals is no longer available Python3 import numpy as np import pandas as pd The order of the selected integers is undefined.
