摘要: In this article, authors introduce a method to assess local influence of observations on the parameter estimates and prediction in multivariate regression model. The diagnostics under the perturbations of error variance, response variables and explanatory variables are derived, and the results are compared with those of casedeletion. Two examples are analyzed for illustration.
