▼a Any survey specifically constructed so that at least some variables are unobserved on a subset of participants is a planned missing data design, where missing data represent an intentional feature of the study. Use of planned missing data design |

▼a First, we propose new methods for selecting our second phase sample in two-phase surveys to reduce the variance of our estimate. When our outcome variable is continuous, we can use the data collected in Phase I for selecting our Phase II sample |

▼a Next, we examine the performance of several design allocations for implementing a split questionnaire survey in a longitudinal study. While many papers examined the administration of split questionnaire designs in cross-sectional studies, resear |

▼a Finally, we propose a method for improving variable allocation in split questionnaire designs. We establish a criterion that allows us to determine which variable allocations minimize the loss of information due to missing data. We use the Kullb |
