pandas EWMA documentation possible error
I believe there might be an error in the documentation for the pandas EWM method at 

http://pandas.pydata.org/pandas-docs/stable/user_guide/computation.html#exponentially-weighted-windows

in particular, in the following line:

> When adjust=True we have y0=x0 and from the last representation above we have yt=αxt+(1−α)yt−1, therefore there is an assumption that x0 is not an ordinary value but rather an exponentially weighted moment of the infinite series up to that point.

shouldn't "adjust=True" be replaced with "adjust=False"? 

cf. the discussion here:
https://github.com/pandas-dev/pandas/issues/8861.

I might be wrong, in which case apologies. Thanks for your help.
