Topic
How to recover Selection Bias from Sample and Survey Data
Abstract
In Data Science, more often than not, people think the more data the better. However, despite the vast amount of data, the data collection process could determine whether the analysis is biased. In the talk, Anh will present standard techniques to remove the selection bias. When the necessary assumptions do not hold, she provides considerations about how to exploit domain knowledge to recover partially from selection bias, which in some cases result in informative bounds. The methodology has several advantages: (1) It operates non-parametrically based on the causal graphical model which is less sensitive to model misspecification; and (2) it does not rely on having the selection probability which is not always available. This methodology is very useful especially in extrapolating results from survey samples to the whole population, and in any causal analysis.
