This paper mainly studies the problem of missing response under the linear regression model, systematically summarizes the development situation, and introduces the research background and significance of missing response variables. The following focus: the first step is to build a missing model of linear regression response.In the second step, the two aspects of mean interpolation and observation data estimation are studied in detail respectively, and the specific mathematical formulas are given. In the third step, the estimate of regression coefficient, mean, distribution function, quantile under "complete sample" based on missing value and based on part number.
