#1191: stats.distributions std with vector args
-------------------------+--------------------------------------------------
 Reporter:  josefpktd    |       Owner:  somebody
     Type:  defect       |      Status:  new     
 Priority:  normal       |   Milestone:  0.8.0   
Component:  scipy.stats  |     Version:  0.7.0   
 Keywords:               |  
-------------------------+--------------------------------------------------
 Looking at some recent changes:

 I think

 {{{
 >>> stats.t.std([5,6])
 array([ 1.29099445,  1.22474487])
 }}}

 does not work after
 http://projects.scipy.org/scipy/changeset/6463

 because of the use of math.sqrt

 {{{
 >>> math.sqrt(stats.t.stats([5,6]))
 Traceback (most recent call last):
   File "<pyshell#9>", line 1, in <module>
     math.sqrt(stats.t.stats([5,6]))
 TypeError: a float is required
 }}}

 but I haven't run current trunk yet

 A note:
 I don't think the stats() method works for array_like args for all
 distributions, and there are still open tickets and insufficient tests for
 array_like shape parameters for other methods.
