以影响函数的有界性来描述估计量的局部稳健性。
The local robustness is described by the bounded Influence Function.
重权数方法与重抽样方法类似，也是利用计算机的优势通过重复获得大量不同的子样本的重权数估计目标参数的估计量和方差估计量，是一种稳健、通用、有效的方差估计方法。
Replicate weight, which is similar with replicated sample method, gets a lot of replicated weights to obtain the estimators by computer, it is also a robust, common and effective method.
