信号在背景上的可观测性
On Observability of Signal over Background
摘要:
几个统计物理学家用来宣布的信号的可观测性的背景进行了比较。它表明,频率论的方法来检验一个精确的假设,允许一个估计的功率值的标准与指定的显着性水平所考虑的统计Monte Carlo计算。讨论了该方法在实验发现潜力分析中的应用。
英文摘要:
Several statistics used by physicists to declare the signal observability over the background are compared. It is shown that the frequentist method of testing a precise hypothesis allows one to estimate the power value of criteria with specified level of significance for the considered statistics by Monte Carlo calculations. The application of this approach for the analysis of discovery potential of experiments is discussed.
