There has been some discussion, initiated by W.J. Heeringa, on the
definitions of quar(n)tiles used by various statistical packages.
I have found the following reference useful in this regard, though by
now partially outdated:
Author = {Frigge, Michael and Hoaglin, David C. and Iglewicz, Boris},
Title = {Some Implementations of the Boxplot},
Year = 1989,
Journal = {The American Statistician},
Volume = 43,
Pages = {50--54},
Keywords = {[Statistical Computing]; Exploratory data analysis;
Outlier; Software; Graphics}
Best,
Rick.
