Some Generalizations of the Mitofsky-Waksberg Technique for Random Digit Dialing
本文提出一类两阶段随机拨号抽样技术，推广了Mitofsky-Waksberg方法，允许更灵活的电话号码分类和每初级抽样单元抽取多个号码，以降低第二阶段复杂度。
Abstract Abstract To provide greater flexibility and improved methodology for random digit dialing for telephone surveys, this article proposes a class of two-stage sampling techniques for random digit dialing that generalizes the Mitofsky–Waksberg technique in two directions. First, different ways of classifying telephone numbers are allowed; the classification need not be according to whether or not the number is residential. Second, drawing more than one phone number per primary sampling unit is allowed in the first stage, with the result that complexities in the second stage can be reduced.
