Abstract
A model in which factor means and factor covariances vary continuously with an external variable is discussed. We assume that, if the covariance matrix of manifest variables should have a certain structure, the means should also have a certain structure characterized by latent variables. In this paper, we discuss two kinds of models. The first is a model in which both means and a covariance matrix of latent variables are functions of an external variable. The second model has structure on the means of manifest variables, but the covariance matrix of the manifest variables is non-structured and constant across the values of the external variable. Finally, the models were fit to the real data in which an external variable “age” was assumed to influence both the means and covariances of the latent variables.
