population variance

基本解释

The sample breakdown point of a test for moment estimation of population variance;
检验的样本崩溃点是样本中能逆转判决的离群值的最小比例。
They divide by n-1 to make it an unbiased estimator of the population variance, but I'm just going to show it in a simple way here.
当除以n-1表示的是对总体的,无偏估计,我在这里只是说的简单一点
In this paper, We give the sample breakdown point of a test for moment estimation of population variance and analyze the asymptotically normal characteristic of the sample breakdown point.
本文给出了总体方差矩估计检验的样本崩溃点，并分析了该样本崩溃点的渐近正态性。
