Vera Toepoel and I have been writing a few articles over the last two years about how survey respondents are taking up tablet computers and smartphones. We were interested in studying whether people in a probability-based web panel ( the LISS panel ) use different devices over time, and whether siwtches in devices for completing surveys are associated with more or less measurement error.
In order to answer this question, we have coded the User Agent Strings of the devices used by more than 6.
Frauke Kreuter once commented on a presentation I gave that I should really be looking at sequence analysis for studying attrition in panel surveys. She had written an article on the topic with Ulrich Kohler ( here ) in 2009, and as of late there are more people exploring the technique (e.g. Mark Hanly at Bristol, and Gabi Durrant at Southampton ).
I am working on a project on attrition in the British Household Panel, and linking attrition errors to measurement errors.
