摘要
等值标准误是描述等值随机误差的一个非常有效的指标。本文从等值标准误的角度,结合实测数据,使用Bootstrap方法对预光滑等百分位等值、后光滑等百分位等值以及未光滑等百分位等值三种方法的随机误差进行了实证研究,以探究在不同光滑方法下随机误差的变化。
Equivalent standard error is a very effective indicator for describing equivalent random errors.In this paper,from the perspective of the equivalent standard error,combined with the measured data,the Bootstrap method was used to conduct empirical research on the random errors of several equivalence methods,such as presmooth equipercentile equivalence,post-smooth equipercentile equivalence and unsmooth equipercentile equivalence,soas to explore the changes of randomerrors under different smoothingmethods.
