Hi,
i am working on a data set with EDA. That includes QQ-Plots of
residuals vs expected normal distribution.
What puzzles me is that the range of ordinate and abscissae is
so different: while the theoretical quantiles range from [-2, 2]
the sample quantiles on the ordinate do extent from [-20, 50].
Quite obviously some kind of transformation is done.
Although i intensively RTFM i could not find, what is done here.
What exactly characterizes the range of the ordinate in QQ-Plots ?
cheers,
Fred
