| Abstract: | The main result of this paper is the theorem,which gives the upper bound of the influence on fittedvalues,whole severable datas are deleted at one time.In this paper,we get the lower bound of the influ-ence on fitted values,and it makes the influenle of datas on the fitted values more definite. |
