WebJul 16, 2014 · To plot the empirical CDF you can use matplotlib 's plot () function. The option drawstyle='steps-post' ensures that jumps occur at the right place. However, you need to force a jump at the smallest data value, so it's necessary to insert an additional element in front of x and y. WebJul 21, 2024 · The parameters of the Weibull can be very difficult to estimate. You should consider something similar to the K-S test as a conservative scoring. It has a clearly understood meaning as well. Weibull estimation has a long history of fitting the CDF to the parameters either graphically or by numerical means.
