#1295: Confusing and/or inaccurate labels on probability plot ('stats.probplot')
 Reporter:  jmpolom      |       Owner:  somebody

 Priority:  normal       |   Milestone:  0.9.0       
Component:  scipy.stats  |     Version:  0.7.0       
 Keywords:  probplot     |  

Comment(by jmpolom):

 I think that's a fairly technical question that should be answered by
 someone well-versed (career statistician) in the topic. When I talked with
 a professor in the industrial and manufacturing engineering department at
 Wayne State University (USA, MI), they were confused what the title meant
 as they had never heard of such a thing. He was familiar with median rank
 statistics but then that means the theoretical quantiles are derived from
 a very specific type of rank stat. Possibly true. I know one statistician
 and he might be able to help. Next time I see him, I'll try to remember
 and ask.

 The more general axis label would be "theoretical quantiles" as is the
 case for normal prob plots in R (qqnorm). Since it'd be hard/excess
 complication to implement a feature for automatically labeling the axis
 according to distribution, changing the axis label to 'theoretical
 quantiles' might be wise.
