| Abstract: | The influence of data deleted on Almon estimator is discussed in this paper.W-K statistics which is established can assess the influence of data on Almon estimator when a set of cases are removed.Inequality relation between W-K statistics and generalized coefficient correlation is built. |

| Keywords: | linear model Almon estimator generalized coefficient correlation |
