摘要：
An extension of the growth curve model of Potthoff and Roy (1964) is presented. The extension arises naturally when parallel profiles are required, or profiles are concurrent at some known time point and may be of use for th analysis of longitudinal data from designed experiments. Linearization of a nonlinear model also results in this model. Under certain conditions, transformation of the model leads to seemingly unrelated multivariate regressions. In this case questions of identifiability and estimation are handled easily. An analysis of data on the growth of lambs is presented to illustrate the approach.
