管理科学与工程系学术讲座:A Change-of-Variables Approach to Simulating Conditional Expectations
发布日期: 2015-06-16

 Title:  A Change-of-Variables Approach to Simulating Conditional Expectations

Speaker: Guangwu Liu, City University of Hong Kong

Time: 14:00-15:00, pm., 19, Jun. (Fri.), 2015.

Venue: Room 404, Tongji Building A

Abstract:

Typically crude Monte Carlo estimators do not perform well when estimating conditional expectations, which may be expectations conditioned on a probability-zero event. In this talk we introduce a change-of-variables approach to simulating conditional expectations. At the heart of the proposed approach is the construction of a one-to-one mapping such that a conditional expectation can be represented as an ordinary expectation by using change-of-variables technique. This new representation leads to an efficient estimator of the conditional expectation. Application to Greek estimation for financial options will be discussed.
