Overview

This site hosts some technical notes on work in progress, for a study on "Missed Detections: From Data to Actionable Estimates.. The project is funded by the Borders, Trade and Immigration Institute (BTI) at the University of Houston. The Principal Investigators area Paul B. Kantor, Dennis E. Egan, and Fred S. Roberts. For additional information please contact any of us using the information on our web sites.

Social Science Perspectives

Several of the project reports focus on whether social science can tell us something useful about the probability that specific classes of persons are deterred by the application of specific measures (called "consequences"). Our research has yielded some indication of the potential of these approaches, and an overview of diverse data sources.

Mathematical Models for Extended Capture-Recapture (ECR)

Other reports examine some novel models that seek to combine available information, which may come from apprehension and re-capture records, from expert assessment, or from computer simulations. The relevant reports are listed below.

Data Envelopment Analysis (DEA)

The project also began exploration of whether the techniques of DEA might provide an alternative to conventional econometric analysis in estimating the impact of specific resources on the security of the border. DEA is distinguished from more conventional methods by its ability to account for important variations in context and constraints, among the several parts of the border security overall effort.
