| Abstract: | The empirical likelihood confidence interval is constructed for the mean of response variables in linear regression model when the independent and the response variables all have missing.Our simulation indicates that the adjusted empirical likelihood confidence regions have good coverage accuracies and average lengths,which perfected the study of linear regression model with missing data. |
