This is the home page of SIPTA (*Society for Imprecise Probability: Theories and Applications*).

Here you can find information about the conferences and the schools that the Society organizes.

We also provide some sources for information about imprecise probabilities mantained by SIPTA.

A description of the Society, its aims, articles and executive committee is reported, too.

**Announcements**

- The 9th ISIPTA Conference will be held in Pescara, Italy, on July 20-24, 2015.
- The seventh Workshop on Principles and Methods of Statistical Inference with Interval Probability (WPMSIIP) was held in Ghent.
- The SIPTA Blog is now online! The blog is edited by our Executive Editor. Everyone in the SIPTA Community can contribute! Please contact the Executive Editor if you are interested in doing so. We see it as an electronic continuation of the Newsletter, so do not hesitate to send us contributions (reports on meetings, book or recent literature reviews, interviews, software presentations,...) or request an account in case you would like to make regular posts.
- The 6th SIPTA summer school was held at the university of Montpellier, France, from 21th to 25th July 2014. More information here.
