Webinar Abstract
Multiple frame surveys, in which samples are selected independently from overlapping sampling frames, can improve population coverage, increase sample sizes for subpopulations of interest, and reduce costs. I review classical multiple frame survey theory for probability samples and extensions to nonprobability samples. Assumptions for estimators from multiple frame surveys to be unbiased with the claimed variance are strong, and when the assumptions are not met estimators from a multiple frame survey may have higher mean squared error than estimators from a high-quality single frame survey. I look at multipurpose designs that can detect violations of assumptions in addition to providing estimates of population characteristics.
