Emeritus professor of Statistics at the Faculty EWI (Electrical Engineering, Mathematics and Computer Science) of the University of Technology, Delft.
Member of DIAM (Delft Institute of Applied Mathematics) at Delft University.
Book with co-author Geurt Jongbloed (published December, 2014),
see:
Nonparametric Estimation under Shape Constraints
Review of the book in Mathematical Reviews of MathSciNet of the American Mathematical Society:
review.
Annotations and corrections for the book are listed in Annotations for book.
In the years 2020-2023 I was columnist of Nieuw Archief voor Wiskunde (NAW).
My columns were in chronological order:
The Netherlands in Times of Corona (in Dutch)
The Statistics Scene
Two cultures
En flagrant délit (with comments)
This column was inspired by an article in Leiden's University Weekly "Mare":
Fraud, disappearing evaluations and a toxic environment
The rejoinder to the comments of the Leiden University authorities after my column is given here: rejoinder
Chernoff's distribution and the bootstrap
Monty Hall, Marilyn vos Savant en Fermat
Wortel min 1 bestaat niet!
Danse Macabre
Chernoff's law and Jante's law
Buffon's needles and noodles
Convex Hulls
The latter column discusses central limit theorems for the number of vertices
and the area of the convex hull of a uniform sample in the interior of a convex planar set. It discusses
in particular the relation between results of this type in a paper of mine from 1988 and two papers of
John Pardon from 2011 and 2012. John Pardon is a recipient of the Fields medal 2026 and for this occasion there is an interesting
video where we see him play the cello, teach his children Chinese and juggling:
John Pardon
He plays the first movement of the beautiful cello sonata opus 69 by Beethoven, accompanied by Jaehyun Park on the piano, in
Beethoven, opus 69
I enjoyed this video very much, although John unfortunately is only half
visible here. The sound quality also leaves something to be desired.
Nevertheless, we should also have more videos of mathematicians performing musical pieces available in our country!
The Mathematical Institute of the University of Amsterdam has (almost) yearly concerts
(musical evenings), but I am not aware of any videos or sound fragments of these events on internet.
ChatGPT (with Lambert Meertens)
Lucia de Berk was a nurse who was accused of several murders and attempted murders. In the calculation of the law psychologist Henk Elffers,
the probability of experiencing a number of incidents (14) that led to Lucia's conviction
was about one in 342 million. However, in the calculations, presented in the American journal "Chance",
we got a probability of about one in 46. The paper can be found on p. 9 to 15 of the 2018
issue of Chance, with authors Richard Gill, Peter de Jong and myself:
Elementary Statistics on Trial - The case of Lucia de Berk
The "two ducks" in the Fokke and Sukke cartoon are in fact a canary and a duck (still corrected in the online version of Chance,
Volume 31, Issue 4, 2018, which is however behind a paywall; I use the version they sent me). I am very grateful to Jean-Marc van Tol for sending
this version of the cartoon to me and providing it with an English text on rather short notice.
In 2008, Lucia de Berk was allowed to
wait for the end of the legal proceedings from outside prison, and two
years later she was finally acquitted
of all murder accusations. She died at age 63 in 2005.

On August 6 and 7, 2013, I delivered the Wald lectures at the Joint Statistical Meeting in Montreal:
