Abstract:
|
Arbitron continually collects data on radio listening from survey samples of people in close to 300 media markets across the United States. Users of the data have access to a web-based application that can be used to generate audience estimates for customizable sub-populations defined by the intersection of a number of dimensions: demographic, socio-economic, geographic, time of day. All told, there are billions of possible audience estimates.
In 2010, Arbitron released a web-based application that allows the user to generate confidence intervals for any of these estimates. The tool is based on generalized variance function methodology. In this presentation, we describe the tool and its associated GVF, examine the underpinnings of the variance estimation methodology, and report on an evaluation of the GVF.
