| Abstract: | In this article,we consider the influence analysis of the seemingly unrelated regression model.By using the method ofcase deletion,we give the specific formula for two approximate likelihood distances basing on the double derived function and its expectation of the likelihood function.Moreover,the conclusion is illustrated by an example. |
