Professional Interests

• Statistical Computing Environments: Primarily R: I'm member of the R Core Development team and the R Foundation for the R Project.
  In 2014, there's been a nice interview (by Rebecca Wyss;   English or Deutsch) about me and my involvement with R.
  R originated as "dialect" of S which I had heavily used and propagated (also in its commercial version "S-PLUS"), before R matured beyond S.
  Slightly even more in the past, X-Lispstat had been novel and influential.
• Emacs Speaks Statistics =: ESS. I've been a Core Developer since about 1997, and am ESS project leader since August 2004.
• Clustering Algorithms (in teaching, also by maintaining the recommended R package cluster.
• Robust Statistical Methods (notably implementation with R: maintaing R package robustbase and the CRAN task view about robust statistical methods, Robust).
• Sparse Matrix algorithms and their implementation in R via S4 classes and methods, notably by co-maintaining the R package Matrix.
• `Wp' Smoothing (see Info); and simplifications of that approach, e.g., in R package cobs that I maintain.
• Variable Length Markov Chains (with R package VLMC and a publication in JCGS)
• Mailing List management, and spam filtering: I'm co-managing two dozen mailing lists, most notably the ones related to R
  .

Teaching

Slides (and Sweave snippets) of my invited talk "Good Practices for R Programming",
at useR! 2014 at UCLA.

see the Seminar für Statistik's lectures' page, and maybe also my miscellaneous collection of teaching material.

A xkcd comic depicting a (typical ?!) abuse of statistical significance testing.

Manuscripts

diverse unpublished manuscripts are available here.
