Fix

[KatIsHere]

Hello, Sir,
I would like to question you about this part in "hurst":
"
elif kind == 'change':
incs = series
_series = np.hstack([[0.],np.cumsum(incs)])
mean_inc = (series[-1] - series[0]) / len(incs)
deviations = incs - mean_inc
Z = np.cumsum(deviations)
R = max(Z) - min(Z)
S = np.std(incs, ddof=1)
"
shouldn't it be there like this
"mean_inc = (_series[-1] - _series[0])/len(incs)"?
Sorry in advance if I am wrong.

Thanks for the notification!
Previous code was overcomplicated. I improved it a bit.

hurst/hurst/__init__.py

Lines 93 to 99 in bfcd29f

	elif kind == 'change':
	incs = series
	mean_inc = np.sum(incs) / len(incs)
	deviations = incs - mean_inc
	Z = np.cumsum(deviations)
	R = max(Z) - min(Z)
	S = np.std(incs, ddof=1)
