| Abstract: | In this paper the influence upon the ridge estimator which is caused after deleting one or more groups of data in linear model is measured by generalized variance ratio.The expression of generalized correlation coefficient between the ridge estimators before and after deleting datum is given.Some general results are acquired,too. |
