## 截尾回归模型参数估计的性质

The Nature of the Truncated Regression Model of Parameter Estimation
Abstract: In many areas of science research, whether it is agriculture, economics and all kinds of engineering, there was no doubt become indispensable in our work and life ，it became an important part of our life and work. And censored data is more common in the statistical data, the properties of statistical application in censored data binding method of statistical inference and hypothesis testing methods, are very good solution to some problems. This paper is mainly on existing knowledge system and a variety of related research results in the foundation, with a truncated distribution theory, regression model, parameter estimation method and censored regression case parameter estimation properties were further discussed.
Keywords:Truncated distribution; Regression model ; Maximum likelihood estimation;Gradual normality
