I've been giving my share of presentations lately about the work of the AAPOR Online Panels Task Force, some of them to interested parties outside of the standard AAPOR constituency. Early on I always mention that we organized our literature review around the Total Survey Error Model (TSE) and I've learned that not everyone is totally clear about what I mean. How timely then that POQ has just come out with a special issue devoted to TSE. And has been their habit with special issues lately, it's available to all, subscribers and non-subscribers alike. At least have a look.
