Wolfgang-Wetzel-Preis
To promote outstanding young scientists and young scientists of the board of the German Statistical Society writes the Wolfgang Wetzel Award from the DStatG for the year 2019. The award is named after the former chairman of DStatG, which began during his tenure, especially for strengthening the mathematical and statistical methods in society.
The prize is awarded to young scientists and young researchers up to five years after graduation for an outstanding contribution to the statistical methodology and its application. The Laureate contribution is usually from an already published or at least accepted for publication.
