数量特征敏感性问题调查模型的改进——基于Greenberg模型与随机变量和模型的系列改进模型

An Improvement on the Investigation Model for Sensitive Problems with Quantitative Character——Series Improved Models Based on Greenberg Model and Random Variables Model

以Greenberg模型与随机变量和模型为基础,提出一种提高估计精度的思路,即:以递减的概率引入随机数与敏感性问题数值进行运算,依次提出各种改进模型,在一定条件下,可以缩小估计量的方差,提高精度.

The Greenberg model and Random variables model are adopted for improving the evaluation accuracy, namely, Random numbers introduced to the model by decreased probability are used to compute the numbers of sensitive problems with quantitative character, which makes the evaluation of average value more accurate.
