Seemingly Unrelated Regressions
This article considers the seemingly unrelated regression (SUR) model first analyzed by Zellner (1962). We describe estimators used in the basic model as well as recent extensions.
متن کاملBayesian modelling of multivariate quantitative traits using seemingly unrelated regressions.
We investigate a Bayesian approach to modelling the statistical association between markers at multiple loci and multivariate quantitative traits. In particular, we describe the use of Bayesian Seemingly Unrelated Regressions (SUR) whereby genotypes at the different loci are allowed to have non-simultaneous effects on the phenotypes considered with residuals from each regression assumed correla...
متن کاملEstimation of Seemingly Unrelated Tobit Regressions via the EM Algorithm
In this article we consider the estimation of two seemingly unrelated Tobit regressions in which the dependent variables are truncated normal. The model is useful, since it can be viewed as the reduced form of a simultaneous-equations Tobit model. The proposed estimation method and algorithm are interesting in themselves for the following reasons. In the estimation of a simultaneous equations m...
متن کاملExact Tests for Contemporaneous Correlation of Disturbances in Seemingly Unrelated Regressions
This paper proposes finite-sample procedures for testing the SURE specification in multi-equation regression models, i.e. whether the disturbances in different equations are contemporaneously uncorrelated or not. We apply the technique of Monte Carlo (MC) tests [Dwass (1957), Barnard (1963)] to obtain exact tests based on standard LR and LM zero correlation tests. We also suggest a MC quasi-LR ...
متن کاملEstimating parameters for tree basal area growth with a system of equations and seemingly unrelated regressions
A method was developed for estimating parameters in an individual tree basal area growth model using a system of equations based on dbh rank classes. The estimation method developed is a compromise between an individual tree and a stand level basal area growth model that accounts for the correlation between trees within a plot by using seemingly unrelated regression (SUR) to estimate the restri...
