讲座主要内容：

This talk presents well-known and new properties of the Student-t distribution. Some of the properties improve the modelling ability for robustness and some make the model implementation of the Student-t distribution as easy as the normal distribution using Bayesian computational methods. A new non-elliptical multivariate Student-t distribution will be introduced. Actuarial and financial applications are given.
