Yes, I am interested in this.

This is partially true..
I think I should have explained more of my research question. My program is
generating a real number variate X for every success. I keep on storing X
for each success cycle of my program and once the sample list is size 1000;
then I would like to use that sample space to determine the probability for
every next X and again store it until the sample space reaches 1000.
I am not really concerned with the distribution type of my sample space, so
i thought (may be out of ignorance) that I first must determine the
distribution type using the fit function and then get the mean/std. Once I
have mean/std, then i get CDF probability for every next X and store it my
sample list replace the previous once.
Basically, I want to get a probability for every X in my program cycle till
the next sample space reaches 1000, and keeps on doing it. This way I am
assuming my algorithm will learn to improve.
But I could not figure out the proper python code yet for this....
Thanks,
Omer
