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

Shallow water inertio-gravity Poincaré waves in a rotating frame satisfy the Klein–Gordon equation, originally derived for relativistic, spinless quantum particles. Here, we compare these two superficially unrelated phenomena, suggesting reason them sharing same equation. We discuss their energy conservation laws and equivalency between non-relativistic limit of yielding Schrödinger near-inerti...

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.

We uncover a connection between two seemingly unrelated notions: lettericity, from structural graph theory, and geometric griddability, the world of permutation patterns. Both these notions capture important properties their respective classes objects. prove that are equivalent in sense class is geometrically griddable if only corresponding inversion graphs has bounded lettericity.

T his study evaluates the causality relationship between human capital and foreign direct investment inflow in twenty-six OIC (the Organization of Islamic Cooperation) countries over the period 1970–2014. We employed the panel Granger non-causality testing approach of Kònya (2006) that is based on seemingly unrelated regression (SUR) systems, and Wald tests with country specific boot...

The aim of this study was to develop and evaluate models for predicting the carcass composition of lambs. Forty male lambs were slaughtered and their carcasses were cooled for 24 hours. The subcutaneous fat thickness was measured between the 12th and 13th rib and breast bone tissue thickness was taken in the middle of the second sternebrae. Left side of carcasses was dissected and the proportio...

In this article, we present estimates of regional softwood lumber supply functions in the United States using annual time series data for 1959 to 2009. Seemingly unrelated regression is used in a profit maximization framework to model softwood lumber supply as a function of lumber and stumpage prices, lagged supply, wage rate, and interest rate for the eastern and western United States. The eff...
