#1200: consistency of std interface
 Reporter:  amcmorl                     |       Owner:  somebody   
     Type:  defect                      |      Status:  new        
 Priority:  normal                      |   Milestone:  Unscheduled
Component:  scipy.stats                 |     Version:  devel      
 Keywords:  signature, ddof, bias, std  |  
 scipy.stats.nanstd and numpy.std have different signatures, which should
 be made consistent:

   scipy.stats.nanstd(x, axis=0, bias=False)


   numpy.std(a, axis=None, dtype=None, out=None, ddof=0)

 Most important is changing the bias keyword to ddof.
 The dtype parameter may not be relevant to nanstd since nans only exist in
 floats (what about complex?).
