# 利用次序截尾数据线性回归方法推断正态总体的未知参数Using Order Censored Data Regression Method to Infer the Normal Overall Unknown Parameter

Abstract: The characteristics such as sample data amount, good integrity, and meeting the random drawing are often required in using the method of sampling analysis for parameter estimation and inference in statistics. However, in practice we are often faced with a series of order censored data, and the parameter error obtained by the usual estimation methods may be very big. In this paper, the method of regression analysis was used to deduce the overall parameters by using the order truncation data and to do the simulation calculation. It is shown that the method is feasible by comparing the error. Finally we used the method to solve the problem about estimating the overall average score by using some sort of student achievement.
