The areas of overlap of confidence intervals from several studies can be used to create summary confidence regions. These summary regions lend themselves to graphical display, have readily derivable statistical properties, and can carry information about the influence both of available studies and of hypothetical future investigations. The case of a region covered by at least N-1 out of N confidence intervals is presented in some detail.
来自多项研究的置信区间的重叠区域可用于创建汇总置信区域。这些汇总区域便于图形展示,具有易于推导的统计特性,并且能够承载有关现有研究以及假设的未来调查的影响的信息。文中详细介绍了一个由N个置信区间中的至少N - 1个所覆盖的区域的情况。
