Title:
Dealing with Latent Pre-exposure to Information Treatments

Abstract:
In Social Sciences, many experiments rely on responses to information
treatments. Experimental subjects in the treatment group receive some
information that subjects in the control group don't. Often, the
proportion of people in the treatment and control groups who were
pre-exposed to the information is unknown and uncontrolled by the
researchers. If that pre-exposure is ignored, it can bias the treatment
effect estimation and lead to incorrect conclusions. I propose two
estimation procedures for latent pre-exposure in this paper. One combines
designed-based and model-based methods and relies on ancillary sampling
and predictive probability of pre-exposure. The other is data-driven and
relies on exploring latent effect heterogeneity using unsupervised
learning methods and Dirichlet Process models. I compare both approaches
using a real application to investigate public attitudes toward government
tax policies to reduce economic inequality.


------------------------------------
Sponsored by the UCR Data Science Center, the purpose of the Data Science
Seminars is to foster collaborations between "core" Data Science faculty
(from CSE/ECE/Stat Departments) and faculty/visitors from other sciences
that face Data Science problems in their research. These informal
gatherings are open to interested faculty and graduate students. Each
meeting will start with a talk describing research problems and then a
discussion will follow for questions, open problems, ideas for possible
collaborations etc.

lab that may be interested. Moreover, if you are interested in giving a
