Careful design of a dual-frame random digit dial (RDD) telephone survey requires selecting from among many options that have varying impacts on cost, precision, and coverage in order to obtain the best possible implementation of the study goals. One such consideration is whether to screen cell-phone households in order to interview cell-phone only (CPO) households and exclude dual-user household, or to take all interviews obtained via the cell-phone sample. We present a framework in which to consider the tradeoffs between these two options and a method to select the optimal design. We derive and discuss the optimum allocation of sample size between the two sampling frames and explore the choice of optimum , the mixing parameter for the dual-user domain. We illustrate our methods using the , sponsored by the Centers for Disease Control and Prevention.
精心设计双框架随机数字拨号（RDD）电话调查需要从众多对成本、精度和覆盖范围有不同影响的选项中进行选择，以便尽可能地实现研究目标。其中一个需要考虑的因素是，是否要筛选出手机用户家庭，以便对仅使用手机的家庭进行访谈，并排除双用户家庭，还是接受通过手机样本获得的所有访谈。我们提出了一个框架，用于考虑这两种选项之间的权衡，并给出一种选择最优设计的方法。我们推导并讨论了两个抽样框架之间样本量的最优分配，并探讨了最优选择，即双用户领域的混合参数。我们使用由疾病控制与预防中心赞助的[具体项目名称未给出]来说明我们的方法。
