Luiz de SOUZA[1]

Antonio Francisco IEMMA[2]

§    ABSTRACT: The aim of this work is to study incomplete longitudinal data using growth curve models. Under the assumption of a first-order autoregressive process for the errors covariance matrix, maximum likelihood estimators of the parameters of a proposed model, are obtained,. Test of hypothesis CxU = q are performed using Wald’stastistics.

§    KEYWORDS: Longitudinal data; growth curves; autoregressive process.
