华东理工：滑铁卢大学Dinghai Xu副教授学术系列讲座

　　讲座主题：Mixture Models in Finance: Theory and Applications 系列讲座

　　主讲人：Dinghai Xu，PhD, Associate Professor，University of Waterloo

　　邀请部门：金融学系、金融工程研究所

　　讲座概要：

　　The workshop series provide an introduction of mixture models in the area of finance, with a special focus on the applications in financial time-series modelling.

　　A distributional assumption of returns on financial assets is known to play an important role in both financial modeling and its applications. Mixture distributions assume great flexibility, and thus have been popularly used in various financial models, such as autoregressive moving average models, autoregressive conditional heteroscedasticity models, etc. As a note, any continuous distribution can be approximated arbitrarily well by an appropriate Gaussian mixture. The workshop series will discuss some fundamental statistical properties of Gaussian mixture with the Moment Generating Function (or Characteristic Function). Several popular estimation procedures will also be reviewed in the class of minimum-distance estimators. Some recent development (papers) in mixture financial models will be introduced.
