In this paper, we propose a method for the analysis of growth curve models when also the regressor variable may be measured with errors. Two classes of structure for errors in regressors are discussed. For complete and balanced data, estimators for the model parameters are derived under the...

This paper considers estimation under the growth curve model of Potthoff and Roy (1964) with random effects. Estimation under a multivariate model is also considered. Estimation under incomplete data and estimation of random effects are also discussed. A numerical example of data on bulls is...
