We compared aberration detection methods requiring historical data to those that require little background by using simulated data. Methods that require less historical data are as sensitive and specific as those that require 3-5 years of data. These simulations can determine which method produces appropriate sensitivity and specificity.
我们通过使用模拟数据,将需要历史数据的像差检测方法与那些几乎不需要背景数据的方法进行了比较。需要较少历史数据的方法与需要3至5年数据的方法一样灵敏且具有特异性。这些模拟可以确定哪种方法能产生合适的灵敏度和特异性。
