Thank you!

The organisers would like to thank the speakers and all participants of the workshop for a very fruitful meeting. See you again soon for the second workshop in the series.

The video recording of the talks can be found here. You can skip between talks using the bookmarks on the left hand menu.

Data analysis is a central part of the scientific method. The discovery and characterisation of exoplanets requires sophisticated statistical methods, to extract weak planetary signals from dominant stellar effects and noisy datasets. Computational capabilities have increased in the past decades giving access for researchers in many fields to Bayesian statistical tools. The exoplanetary community is now using these tools for their analysis routinely: planets detections, planetary atmospheres, high contrast imaging, planet populations etc.

This workshop aims at bringing together researchers from the PlanetS community with experts in Bayesian statistics as well as researchers already employing the Bayesian techniques.

No previous knowledge is assumed. An introductory lecture should bring everyone on the same page.
