Title: Lessons Learned from Collecting and Analyzing High-Dimensional GPS Data on Adolescent Activity Patterns
Author(s): Catherine A. Calder* and Christopher R. Browning and Bethany Boettner and Kori Khan

Keywords: GPS data; missing data; spatial statistics; survey methodology; activity patterns

GPS-equipped smartphones allow researchers to conduct large-scale, population-based studies to understand activity patterns of individuals as they go about their daily lives.  The raw data produced from such studies, however, can be overwhelming to researchers due complexities such as spatial variation in positional measurement error, uncertainty in subjects’ compliance with the study protocol, and the need for novel data reduction strategies that properly acknowledge non-random patterns in missingness.  This presentation will discuss the author’s experience as the lead statistician for the Adolescent Health and Development in Context Study.
