Title Tools for Analyzing Finite Mixture Models Depends R (>= 3.5.0) Imports kernlab, MASS, segmented, stats, survival … hierarchical mix-tures -of- experts ), and tools for selecting the number of components (bootstrapping the likeli-hood ratio test statistic, mixturegrams, and model selection criteria). Bayesian estimation of mix -, The use of Mixture of Experts to integrate clinical variable and microarray data may help refine the prognostic of a disease and increase the prediction accuracy in cancer studies. R -Forge: Mixture of Experts : R Development Page, Mixture of Experts: Project Home – R -Forge. Project description. The use of Mixture of Experts to integrate clinical variable and microarray data may help refine the prognostic of a disease and increase the prediction accuracy in cancer studies. Project Information.
The idea behind mixture of experts is to use a set of linear regressions for each sub space of the original data space and combine them with weighting functions that will successively give weight to each linear regression. Consider the following example dataset, which we generate with the following toy code:, MEteorits: Mixtures -of- ExperTs modEling for cOmplex and non-noRmal dIsTributions MEteorits is an open source toolbox (available in R and Matlab) containing several original and flexible mixtures -of- experts models to model, cluster and classify heteregenous data in many complex situations where the data are distributed according to non-normal and possibly skewed distributions, and when they …
Package MoEClust fits parsimonious finite multivariate Gaussian mixtures of experts models via the EM algorithm. Covariates may influence the mixing proportions and/or component densities and all 14 constrained covariance parameterizations from package mclust are implemented.
8/6/2011 · The mixtools package is one of several available in R to fit mixture distributions or to solve the closely related problem of model-based clustering. Further, mixtools includes a variety of procedures for fitting mixture models of different types. This post focuses on one of these – the normalmixEM procedure for fitting normal mixture densities – and applies it to two simple examples …
