The files in this folder were used to create the findings mentioned in the article 
"The effects of study duration on nonresponse and measurement quality in a smartphone app-based travel diary". 
The datafiles loaded in the code are property of CBS (Statistics Netherlands) and cannot be openly shared. 

If you want to recreate the findings, first you need to get permission to access the data. 
Permission to access can be handled via Barry Schouten (jg.schouten@cbs.nl). As the data we are working with contains micro-data from the population register, you will need to go through several steps to get acces to the data on location (at Statistics Netherlands), and additional steps if you want to get access to the data outside of the country.
