These Departmental Seminars are for everyone in Maths. We encourage anyone interested in the subject in general, or in the particular subject of the seminar, to come along. It's a great opportunity to meet people in the Maths Department and join in with our community.
The large-scale household panel study Understanding Society (The U.K. Household Longitudinal Study UKHLS) has, until recently, used interviewers to administer its questionnaires, but is now in the process of allowing individuals to participate using the web. Survey data are known to be affected by survey mode so a sequential mode-effects experiment was carried out on to evaluate the impact of this change on the panel.
In this talk we present a novel estimator and analysis strategy to quantify the impact of mode across a wide range of variables, with large mode effects on the covariance of a pair of variables used to indicate an increased risk that statistical analyses involving this pair will be affected.
