LLN and CLT

Hi,
I (re)started a study group with students on quant-econ.
Today we found the following:

Regarding illustrates_lln.py, lines 44-46, if I am not mistaken,

    sample_mean = np.empty(n)
    for i in range(1,n):
        sample_mean[i] = np.mean(data[:i])

should be

    sample_mean = np.empty(n)
    for i in range(n):  # range(1,n) -> range(n)
        sample_mean[i] = np.mean(data[:i+1])  # data[:i] -> data[:i+1]

(Should I submit a pull request myself?)

In the code shown in Simulation 1, the following lines are missing:

import numpy as np
from scipy.stats import expon, norm, poisson

Compare the original code.

Yep, good catch on that one. Thanks for reporting.

If you would like to submit a PR for the mistake you found in illustrates_lln.py that would be great.

I will fix the problems in the website now -- although I'm not sure when the updates will appear online.

@oyamad Much appreciated

@spencerlyon2 Please go ahead and merge the fix-lln-clt branch into master in the private repo and close the issue.

Done, thanks!
