Seemingly unrelated clusterwise linear regression for contaminated data

چکیده
Abstract Clusterwise regression is an approach to analysis based on finite mixtures which generally employed when sample observations come from a population composed of several unknown sub-populations. Whenever the response continuous, Gaussian clusterwise linear models are usually employed. Such have been recently robustified with respect possible presence mild outliers in However, some fields research, especially modelling multivariate economic data or social sciences, there may be prior information specific covariates considered term prediction certain response. As consequence, not same for all responses. Thus, novel class proposed. This provides extension mixture-based and correlated responses that let researcher free use different vector each Details about model identification maximum likelihood estimation via expectation-conditional maximisation algorithm given. The performance new studied by simulation comparison other models. A comparative evaluation their effectiveness usefulness provided through real dataset.

Bayesian Geoadditive Seemingly Unrelated Regression
Parametric seemingly unrelated regression (SUR) models are a common tool for multivariate regression analysis when error variables are reasonably correlated, so that separate univariate analysis may result in inefficient estimates of covariate effects. A weakness of parametric models is that they require strong assumptions on the functional form of possibly nonlinear effects of metrical covaria...
متن کاملEfficient Semiparametric Seemingly Unrelated Quantile Regression Estimation
We propose an efficient semiparametric estimator for the coefficients of a multivariate linear regression model — with a conditional quantile restriction for each equation — in which the conditional distributions of errors given regressors are unknown. The procedure can be used to estimate multiple conditional quantiles of the same regression relationship. The proposed estimator is asymptotical...

متن کاملHighly accurate likelihood analysis for the seemingly unrelated regression problem
The linear and nonlinear seemingly unrelated regression problem with general error distribution is analyzed using recent likelihood theory that arguably provides the definitive distribution for assessing a scalar parameter; this involves implicit but well defined conditioning and marginalization for determining intrinsic measures of departure. Highly accurate p-values are obtained for the key d...
متن کاملRobust clusterwise linear regression through trimming
The presence of clusters in a data set is sometimes due to the existence of certain relations among the measured variables which vary depending on some hidden factors. In these cases, observations could be grouped in a natural way around linear and nonlinear structures and, thus, the problem of doing robust clustering around linear affine subspaces has recently been tackled through the minimiza...
