A list with class "htest" containing the following components: There is some more refined distribution theory for the KS test with estimated parameters (see Durbin, 1973), but that is not implemented in ks.test. At first, let’s introduce a statistic of K-S test. NumPy Exponential Distribution (Python Tutorial) - WTMatter Value . Calculate KS Statistic with Python - ListenData 128 Responses to A Gentle Introduction to Normality Tests in Python. # Question 1: # If a website receives 90 hits an hour what is the probability they will go at least 4 minutes between hits# lambda = 1.5 (90 calls an hour / 60 minutes = 1.5 calls per minute)# theta = the average wait time for 1 call = 1 / 1.5 = .66666 The goodness-of-Fit test is a handy approach to arrive at a statistical decision about the data distribution.
