报告题目: Testing Multiple Hypothesis in
Big Data Analysis (大数据分析中的多元假设实验)
报告人： Dr. Zhigen Zhao
报告内容:
When testing one single hypothesis, it is given in every introduction statistics
textbook that one should reject the null hypothesis if the p-value is less than
or equal to alpha, a designated level reflecting one's willingness of
tolerating the type I error. In modern application, it is a common practice for
a scientist to test thousands, or even millions of hypothesis simultaneously.
Can we still use the simple rule stated earlier?
In this talk, I will present
the issue of the multiplicity when testing multiple hypothesis and the recent
development on this area in the last two decades. I will also discuss my recent
work on the construction of the optimal multiple testing procedures using the
decision empirical Bayes approach. I will highlight a few applications with big
data, arising from studies such as the genetics and social science.
