我们提出了一种方法来设置限制,避免排除参数值的灵敏度福尔斯低于指定的阈值。这些“功率约束”限制(PCL)解决了促使广泛使用的CL程序的问题,但这样做的方式,使更透明的统计测试的属性,每个值的参数进行。一个特别令人感兴趣的情况是,参数的上限与尚未确定存在的过程的横截面成比例。然而,功率约束的基本思想可以很容易地应用于其他类型的限制。
We propose a method for setting limits that avoids excluding parameter values for which the sensitivity falls below a specified threshold. These "power-constrained" limits (PCL) address the issue that motivated the widely used CLs procedure, but do so in a way that makes more transparent the properties of the statistical test to which each value of the parameter is subjected. A case of particular interest is for upper limits on parameters that are proportional to the cross section of a process whose existence is not yet established. The basic idea of the power constraint can easily be applied, however, to other types of limits.
