The 32nd edition of the International Workshop on Statistical Modelling (IWSM) takes place in Groningen (NL) in 2017 (3-7 July 2017). IWSM is one of the major activities of the Statistical Modelling Society, founded with the purpose of promoting and encouraging statistical modelling in its widest sense. The spirit of the workshop has always been to focus on problems motivated by real life data and on solutions that make novel contributions to the subject. The atmosphere of the workshop is friendly and supportive, with no parallel sessions, with the aim of stimulating the exchange of ideas and experiences related to statistical modelling. Papers focusing on applications with important substantive implications as well as methodological issues are welcome. Submissions by students and young researchers are particularly encouraged.
