Estimation in Multiple Frame Surveys

In a multiple frame survey, independent samples are drawn from a number of frames whose union is equal to the population of interest, although individual frames might only give partial coverage. For example, the 4th Auckland Diabetes Heart and Health Survey combined samples from two frames, the standard Statistics New Zealand list of census mesh blocks and the Electoral Roll. In this case, the first frame would provide complete coverage of the population of interest (all Auckland residents between the ages of 18 and 74). However the survey specifications stipulated that at least 1000 Maori and 1000 Pacific Islanders be included in the sample and using the Electoral Roll provides a reasonably easy way of achieving this objective.

In this talk, we look at a class of estimation procedures that have two desirable properties. Firstly, they can be implemented using only standard software for single frame surveys and, secondly, the same set of weights is used for all variables. We examine the performance of several members of the class on data from the Auckland Diabetes Heart and Health Survey.
