scipy.stats uses  'standard' arrays.
scipy.mstats uses masked arrays.

Most of scipy.stats was directly implemented for masked arrays in 
scipy.mstats with some additional functionality. So while you can use 
scipy.mstats for non-masked arrays, it is can be 'overkill' and you 
should expect certain consequences such as masked arrays being returned.
