DOC: pandas/pandas/core/window/ewm.py

Location of the documentation

Docstring for class EWM(_Rolling) in ewm.py.

Documentation problem

The purposes of the EWM class is unclear because there's no documentation on what 'ewm' is abbreviating. One reason this is confusing is that ewm can easily be interpreted as either "exponentially weighted mean" or "exponentially weighted moving". The EWM class docstring actually muddies the water further by stating that the class provides "exponential weighted (EW) functions".

Suggested fix for documentation

If it's absolutely necessary to use an abbreviation like ewm then the docstring needs to clearly state what it's abbreviating.
