Title: Risk Analysis: Experience vs Data

How to asses risks with small data sets? One of the challenge in insurance is that despite of having many customers, insurance companies have often little claims data to assess risks. I will presented some Bayesian ideas to analyse risks with little, or even no data. I will touch on ideas from Daniel Kahneman and David Spiegelhalter and play around with Bayesian Belief Networks, hierarchal models and Stan.
