      Finite mixture densities can be used to model data from populations known or suspected to contain a number of separate subpopulations. Most commonly used are mixture densities with Gaussian (univariate or multivariate) components, but mixtures with other types of component are also increas ingly used to model, for example, survival by: A method for parameter estimation in image classification or segmentation is studied within the statistical frame of finite mixture distributions. The method models an image as a finite mixture.

      Mixture models have been around for over years, as an intuitively simple and practical tool for enriching the collection of probability distributions available for modelling data. In this chapter we describe the basic ideas of the subject, present several alternative representations and perspectives on these models, and discuss some of the elements of inference about the unknowns in Cited by: 1.

After the basic definition of mixture distributions, 'many of these.

      Finite mixture densities can be used to model data from populations known or suspected to contain a number of separate subpopulations. Most commonly used are mixture densities with Gaussian (univariate or multivariate) components, but mixtures with other types of component are also increas ingly used to model, for example, survival times. This paper gives a general introduction to the Cited by:   This is the basic idea behind mixture distributions: the response x that we observe is modeled as a random variable that has some probability p 1 of being drawn from distribution D 1, probability p 2 of being drawn from distribution D 2, and so forth, with probability p n of being drawn from distribution D n, where n is the number of components.

The differences between the two mixture distributions that can be pointed out are: (a) The TNW-pdf takes into account the null wind speeds and the WW-pdf, like the W-pdf, does not, (b) As the WW-pdf is a mixture of distributions that are expressed in closed form, notably less calculation time is required than for the by: This volume provides an up-to-date account of the theory and applications of modeling via finite mixture distributions.

INTRODUCTION Flexible Method of Modeling. The importance of finite mixture models in the statistical analysis of data is evident in the ever- increasing rate at which articles on theoretical and practical aspects of mixture models appear in the statistical and general scientific literature.

Abstract. In this chapter, mixtures of certain discrete distributions will be considered. As with mixtures of normals, Pearson () appears to have been the first to study such distributions in any detail, deriving moment estimators for the parameters in a mixture of binomial density by: To incorporate the mixture distributions into the framework of popular generalized linear models (GLMs), the authors propose to use finite mixture models (FMMs) to analyze insurance loss data.

The regression approach enhances the traditional whole-book distribution analysis by capturing the impact of individual explanatory variables.Given a finite set of probability density functions p 1 (x),p n (x), or corresponding cumulative distribution functions P 1 (x),P n (x) and weights w 1,w n such that w i ≥ 0 and ∑w i = 1, the mixture distribution can be represented by writing either the density, f, or the distribution function, F, as a sum (which in both cases is a convex combination).
