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.
