Research Interests

I studied problems on the interface of social, cognitive, and behavioral science and the error properties of social and economic statistics. Such statistical information often arises from sample surveys with measurement based on self-reports of sample units. While the theories of inferences from such measurement systems are straightforward with complete and perfect measurement, such perfection never occurs. Hence, understanding the influences on the existing weaknesses is key to appropriate conclusions on monitoring of modern society. I have attempted to use basic features of classical scientific methods to approach these problems and to build coherent conceptual frameworks to identify research programs.
