| Abstract: | The generalized influence function and generalized Cook distance were used to study local influence of observations on the parameter estimates in the growth curve model with uniform covariance structure.Under the perturbations of error variance,response variables and explanatory variables,the diagnostics were obtained.Finally,an example was analyzed for illustration. |
