In this paper we study the influence of deleting a set of covariates on growth curve estimates. A measure of detecting the influential covariates is proposed. The measure of influence may also serve as a means of selecting covariates in a growth curve model. (E) 1998 Elsevier Science B.V. All fights reserved.

We consider the selection of covariables for the covariance adjustment of parameter estimators in growth curve models. The procedure consists of obtaining the best subset of linear combinations of higher-order polynomials for minimizing the variance of the adjusted estimator of a particular linear c
