[SciPy-dev] scipy.stats: test for handling nan values

[David Cournapeau]

Hi,

    Trying to solve a few tickets related to nanmean and co, I wanted to 
add tests for those functions, as well as general behaviour of basic 
statistics function with nan. Part of the test suite (in test_stats.py) 
is based on the Statistical quiz for Wilkinson; missing values are not 
supported. If I finish the test suite by implemenging MISSING by nan 
values, is this conceptually correct or not ? I wanted to be sure before 
committing the change in the test suite (actually, only adding 
originally disabled tests)

    cheers,

    David
