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
**10th ISIPTA conference**will take place in Lugano from the 10th to the 14th July 2017, and will be collocated with the**ECSQARU**conference. The submission deadline for both conference is the 21th of February 2017 - The 7th SIPTA summer school and 9th Workshop on Principles and Methods of Statistical Inference with Interval Probability (WPMSIIP) were both held in Durham.
- The 8th Workshop on Principles and Methods of Statistical Inference with Interval Probability (WPMSIIP) was held in Munich.
- 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.
