Model-based clustering via skewed matrix-variate cluster-weighted models

چکیده
Cluster-weighted models (CWMs) extend finite mixtures of regressions (FMRs) in order to allow the distribution covariates contribute clustering process. In this article, we introduce 24 matrix-variate CWMs which are obtained by allowing both responses and each cluster be modelled one four existing skewed distributions or normal distribution. Endowed with greater flexibility, our able handle kind data a more suitable manner. As by-product, FMRs also introduced. Maximum likelihood parameter estimates derived using an expectation-conditional maximization algorithm. Parameter recovery, classification assessment, capability Bayesian information criterion detect underlying groups investigated simulated data. Lastly, CWMs, along CWM FMRs, applied two real datasets for illustrative purposes.

Discount Weighted Bayesian Model Averaging for Portfolio Decisions in Matrix Variate Dynamic Linear Models Discount-Weighted Bayesian Model Averaging for Portfolio Decisions in Matrix Variate Dynamic Linear Models
In this paper, we assess Bayesian model averaging (BMA) techniques for dynamic linear models (DLMs) with variance matrix discounting. In previous research, the discount factors for the variance matrices and the auto-regressive lag have typically been pre-determined and held constant over time. Using posterior model probabilities, we average DLMs employing different discount rates and lag parame...
متن کاملDynamic Matrix-Variate Graphical Models
This paper introduces a novel class of Bayesian models for multivariate time series analysis based on a synthesis of dynamic linear models and graphical models. The synthesis uses sparse graphical modelling ideas to introduce structured, conditional independence relationships in the time-varying, cross-sectional covariance matrices of multiple time series. We define this new class of models and...
متن کاملPredictive Matrix-Variate t Models
It is becoming increasingly important to learn from a partially-observed random matrix and predict its missing elements. We assume that the entire matrix is a single sample drawn from a matrix-variate t distribution and suggest a matrixvariate tmodel (MVTM) to predict those missing elements. We show that MVTM generalizes a range of known probabilistic models, and automatically performs model se...
متن کاملClustering and classification via cluster-weighted factor analyzers
Inmodel-based clustering and classification, the cluster-weightedmodel is a convenient approach when the random vector of interest is constituted by a response variable Y and by a vector X of p covariates. However, its applicability may be limited when p is high. To overcome this problem, this paper assumes a latent factor structure for X in each mixture component, under Gaussian assumptions. T...
متن کاملMatrix-Variate Dirichlet Process Mixture Models
We are concerned with a multivariate response regression problem where the interest is in considering correlations both across response variates and across response samples. In this paper we develop a new Bayesian nonparametric model for such a setting based on Dirichlet process priors. Building on an additive kernel model, we allow each sample to have its own regression matrix. Although this o...
