This paper considers the Ridge Feasible Generalized Least Squares Estimator (RFGLSE), Seemingly Unrelated Regression RSUR and proposes Kibria-Lukman KLSUR estimator for parameters of (SUR) model when regressors models are collinear. A simulation study was conducted to compare performance three different types estimators SUR model. Different correlation levels (0.0, 0.1, 0.2, ..., 0.9) among ind...

In this paper we advocate for the idea that two seemingly unrelated mysteries with almost 90 year history -- nature of dark matter and million-degree solar corona may be but sides same coin axions born in core Sun photons axion origin corona, whose modulations are controlled by anticorrelated modulation asymmetric (ADM) density interior.

The usual standard errors for the regression coe cients in a Seemingly Unrelated Regression model have a substantial downward bias. Bootstrapping the standard errors does not seem to improve inferences. In this paper Monte Carlo evidence is reported which indicates that bootstrapping can result in substantially better inferences when applied to t-ratios rather than to standard errors. 3

Abstract We propose a very general, unifying framework for the concepts of dependence and independence. For this purpose, we introduce notion diversity rank . By means identify total determination with inability to create more diversity, independence presence maximum diversity. show that our theory covers variety concepts, example seemingly unrelated linear in algebra variables logic.

The aim of the present paper is to show how a slight generalization of a splitting-off result of Berstimas and Teo [1] offers a common understanding of several seemingly unrelated results in graph connectivity theory.
