| Abstract: | Generalired influence function and generalired Cook distance were used to study local influence of maximum likelihood estimation in the growth curve model with an unknown Rao's simple covariance structure.Under the various kind of perturbation schemes.the local diagnostics of parameter estimates were obtained and an example was used for illustration. |
