Sum of Profiles Model with Exchangeably Distributed Errors
Graciela B. Mentz, Anant M. Kshirsagar · Communication in Statistics- Theory and Methods · 2003
We have considered a generalization of the basic Potthoff–Roy growth curve model by combining a sum of profiles model with an exchangeably distributed errors model. Analytical expressions for the growth curve coefficients and their standard errors are obtain specifically. An illustration where such a model is useful in practice is also supplied.
