#1425: kurtosistest requires at least 4 observations
 Reporter:  bsouthey     |       Owner:  somebody
     Type:  defect       |      Status:  new     
 Priority:  lowest       |   Milestone:  0.9.1   
Component:  scipy.stats  |     Version:  devel   
 Keywords:               |  
 The current implementation of kurtosistest requires that the input must
 have more than three observations. The docstring says 'The Z-score is set
 to 0 for bad entries' so a warning is given and the zeros are returned.
 Technically the masked array version should only set zeros only for those
 indices with less than 4 observations but otherwise work.
