关于二项比例的分裂样本和随机化置信区间

On split sample and randomized confidence intervals for binomial proportions

Måns Thulin

摘要:

分裂样本方法最近被提出作为一种方法,以减少覆盖率振荡困扰的置信区间的参数的点阵分布,如二项和泊松分布。我们研究分裂样本区间的二项式设置,显示这些间隔可以被看作是基于添加离散随机噪声的数据。结果表明,它们可以通过使用噪声与连续分布,而不是改善,无论是由数据或外部来源的随机性的随机化。我们比较分裂样本间隔的随机史蒂文斯间隔,完全消除了覆盖振荡,并发现后者的间隔有几个优点。

英文摘要:

Split sample methods have recently been put forward as a way to reduce the coverage oscillations that haunt confidence intervals for parameters of lattice distributions, such as the binomial and Poisson distributions. We study split sample intervals in the binomial setting, showing that these intervals can be viewed as being based on adding discrete random noise to the data. It is shown that they can be improved upon by using noise with a continuous distribution instead, regardless of whether the randomization is determined by the data or an external source of randomness. We compare split sample intervals to the randomized Stevens interval, which removes the coverage oscillations completely, and find the latter interval to have several advantages.
