Web1 de out. de 2014 · Identifiability. Identifiability results for finite mixtures of ordinary linear models and finite mixtures of GLMs are available, see Hennig (2000) and Grün and Leisch (2008a); but these results are not applicable to models (2.2), (2.3) as some of parameters are nonparametric functions of covariates. Seminal papers of Teicher, 1961, … WebWe analyse the identifiability of the number of components in k-variate, M-component finite mixture models in which each component distribution has independent marginals, including ... Non-parametric identifiability and estimation of finite mixtures has recently attracted increasing attention. Hall and Zhou (2003), Hall et al. (2005)

WebAbstract: Finite mixtures of the following ten families of univariate distributions are shown to be identifiable: logarithmic series, discrete rectangular, rectangular, first law of Laplace, noncentral X^{2}, logistic, generalized logistic, generalized hyperbolic-secant, inverse Gaussian, and random walk.A generalized version of a theorem given by Teicher is used … green chalkboards for saleWebFor 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 … flowlayoutpanel vs tablelayoutpanelWebDuring the past few years, the Gaussian mixture family has attracted considerable attention due to its ability to approximate any continuous distribution using a finite Gaussian mixture model.
