Design and Analysis of Randomized Trials to Estimate Spatio-Temporally Heterogeneous Treatment Effects
估计时空异质处理效应的随机试验设计与分析
In this article, we consider randomized trial design to evaluate interventions with spatially or spatio-temporally heterogeneous effects. A common approach in this setting is the cluster randomized trial. In many cases, clusters are constituted as discrete subdivisions of a contiguous area of interest. However, cluster trials designed in this way may suffer from issues of spillover and may fail to capture the relevant spatial and temporal effects. We define possible…
