Hi, I am trying to write a chi square goodness-of-fit test for Beta distribution from scratch, without using any external functions. The code below reports '1' for a fit, even though kstest from scipy.stats returns a zero. Data is distributed normally, so my function should also return zero. import numpy as np from scipy.stats import ch...

I've seen this argument in a few places, and now, recently i saw it again on a reddit post. This is by no means a flame against any of these two languages.
