Abstract:
|
Arbitron uses a raking procedure to weight the sample from its quarterly surveys to external population controls. Some of these population controls are based on a survey with relatively small sample sizes. They thus contribute to the sampling error found in the final radio listening estimates. In this paper, we examine the results of a detailed empirical investigation into the effect of the stochastic population controls on the precision of the estimators.
