WebFor clustering mixed categorical and continuous data, Lawrence and Krzanowski (1996) proposed a finite mixture model in which component densities conform to the location model. In the graphical models literature the location model is known as the homogeneous Conditional Gaussian model. In this paper it is shown that their model is not identifiable … WebFinite mixtures of continuous densities were first studied by Teicher (1963). Most results for this problem are obtained for distributions on the real line or the d-dimensional Euclidean space. For distributions on the circle, only few examples are known.
