This repo contains the code used for the results in paper: 'Assessing the socio-demographic representativeness of mobile phone application data' in Applied Geography
Given the volume of data being processed, the pre-processing and post-processing of the data for home location estimates are completed using SQL on the database tables. The home location estimates for each of the techniques in this paper are completed in R (between pre and post processing) and results saved back to tables in the database for further analysis
Section 1: relates to the method 'Using activity heuristics only to estimate home location'
Section 2: relates to the method 'Using activity heuristics and land use to estimate home location'
Section 1.1 and 1.2 are the pre-processing steps required for huq/tamoco before standard home detection approach
Section 2.1 and 2.1 are the pre-processing steps required for huq/tamoco before advanced home detection approach
Section 1.3 and 1.4 are reference to the R scripts to performs the standard home detection approach for huq/tamoco
Section 2.3 and 2.4 are reference to the R scripts to performs the advanced home detection approach for huq/tamoco
Section 1.5 - 1.9 are the extraction of population comparisons for the standard home detection approach
Section 2.5 - 2.9 are the extraction of population comparisons for the advanced home detection approach
