发明名称 Survey assignment method
摘要 A survey assignment method uses a weighting factor to compensate for members which are temporarily removed from a panel. This weighting factor allows for non-proportionate samples to be made from the panel. Additionally, a non-proportionate selection weighting factor can also be used. By using these weighting factors, a relatively random selection of the members for survey can be done.
