lshorth: The Shorth Plot
Distribution diagnostics based on the length of the shorth, the shortest interval containing a
specified fraction of the distribution. The diagnostics can be used to detect qualitative features,
such as the modality or skewness of a distribution.
This is an R package accompanying
J. Einmahl, M. Gantner, G. Sawitzki:
The Shorth Plot.
Journal of Computational and Graphical Statistics March 2010, Vol. 19, No. 1: 62 - 73.
and

Asymptotics of the Shorth Plot.
Journal of Statistical Planning and Inference November 2010, Vol. 140, Issue 11, Pages 3003-3012.

Technical notes describing the shorth plot and its statistical background are in
- G. Sawitzki: The Shorth Plot.
- Technical notes. StatLab Heidelberg 1992 (rev. 2007).
The technical notes will be installed as doc/TheShorthPlot.pdf along with the package.
The statistical theory is in
- J. Einmahl, M. Gantner, G. Sawitzki: The Shorth Plot.
- Tilburg University CentER Discussion Papers. 2008.
A revised version is in the publications cited above.
The idea of the shorth plot was first introduced in:
- G. Sawitzki: Diagnostic
Plots for One-Dimensional Data.
- in: Computational Statistics. Papers collected on the Occasion of the
25th Conference
on Statistical Computing at Schloss Reisensburg.
