Anonymous Daily Features Calculated from GPS Data (Beiwe)

GPS data recorded by participants' smartphones and obtained via the Beiwe mobile app. To conserve participant privacy, this dataset excludes raw GPS traces, but contains two aggregated files for each participant instead. The first file contains a daily GPS feature table, including two daily features computed for each day the participant produced GPS data: (1) loc.var, square root of the variance in GPS coordinates recorded on a day; (2) ent.pls, normalized Shannon entropy of the time spent at different significant places. The other file contains an hourly missing status table, indicating whether the participant's smartphone produced GPS data in each hour during the study period.
