Estimating the coefficients in a system of compatible growth and yield equations for Loblolly pine
… in the coefficient estimation procedure. Seemingly unrelated regression techniques were used to estimate the coefficients. The three methods resulted in coefficient estimates that were similar, with seemingly unrelated regression producing the most efficient estimators. Prediction ability …

Pretest Estimators for the Two Sample Linear Statistical Model
… of location parameters in the linear two sample regression problem with possibly a nonscalar error covariance matrix. This problem has been examined before by many authors where identical location parameters were assumed for the two samples, and the covariance matrix had the simplist type of …

Essays on the Effectiveness of Public School Spending and Simultaneous Equation Quantile Regression
The final essay suggests a robust alternative to Seemingly Unrelated Regression (SUR) for two equations. This simultaneous equation median regression estimator is investigated using Monte Carlo simulations. Simulation results support the conjecture that this estimator is unbiased, Normally …

Maximum-likelihood-based confidence regions and hypothesis tests for selected statistical models.
… types of statistical models. The models are a seemingly unrelated regression model, a bivariate Poisson regression model, and a model of two inversely-related Poisson rate parameters with misclassified data. The seemingly unrelated regression (SUR) model promotes more efficient estimation as …

Essays on Semi-parametric Bayesian Econometric Methods
… as special cases of the GLS estimator, the Seemingly Unrelated Regression for equation systems, and the Random Effects Model for panel data, which can be applied to many fields such as the demand analysis in Chapter 1. Chapter 3 focuses on the subset selection for the efficiencies of firms, …

Migration and Children's School and Labor: Evidence from El Salvador
… instrumental variable estimations, as well as a seemingly unrelated regression to estimate the impact of migration on a child’s time allocation. Outcomes are also analyzed measuring the impact of remittances. Results show that children with at least one migrant parent will complete more years of …

Internal stock market returns and systematic risk factors. An empirical investigation into the APT using macroeconomic factors and multivariate estimation
… By employing iterative non-linear multivariate seemingly unrelated regression estimation, this work avoids the statistical problems encountered in the second-pass test of the two-stage procedure. This study found that the international stock market was neither integrated nor efficient and that …

Non-market valuation of urban ecosystem services in Penang, Malaysia
… on improved air quality. The fourth topic uses a Seemingly Unrelated Regression model to explore the impact of spatial data on willingness to pay, showing insights into how spatial characteristics influence preferences. The fifth topic employs a simulation framework to assess the economic benefits …

Modeling the biomass partitioning of loblolly pine grown in a miniature-scale plantation
… correlations among tree components, seemingly unrelated regression (SUR) methodologies led to efficient parameter estimates. When compared to studies with mature trees at operational scales, results from the miniature-scale trees showed similar trends. Stem and woody roots were 70 and …

Economic Development, Social Dislocation and Political Turmoil in Sub-Saharan Africa: A Pooled Time-Series Analysis and a Test of Causality
… employs pooled cross-sectional time-series and seemingly unrelated regression analyses, as well as Granger-causality, to examine the hypothesized relationships and causality in 24 Sub-Saharan African countries from 1971 to 1995. The results confirm the classical economic development theory's …

The effect of price, advertising, and income on consumer demand: an almost ideal demand system investigation
… share system of equations is estimated using the Seemingly Unrelated Regression (SUR) estimation procedure to allow for dependence among error terms and cross-equation coefficients. Theoretically, this research tests the validity of the well established consumer demand theory. It provides an …

Three Essays on Consumer Behavior and Health Outcomes: An Economic Analysis of the Influence of Nutrition Information and Knowledge on Food Purchasing Behavior and the Impacts of Primary Care Givers Parenting on Childhood Obesity
… (BMI). However, the estimates from iterated seemingly unrelated regression (SUR) and semi-parametric polynomial estimation indicate that parents' BMI significantly influence children's BMI. Interestingly, physical activity appears to have weak correlation with children's BMI.

Health management of adult hypertension in the United States: Results from the National Health and Nutrition Examination Survey (NHANES)
… diagnosis and the nutrient intake using the seemingly unrelated regression (SUR) method. The data came from the 2007-2008, 2009-2010 and 2011-2012 cross-sectional National Health and Nutrition Examination Survey (NHANES) which is a sample of the civilian, non-institutionalized adult …

Determinants Of Migration: Inter-european Migration, 1950-1989
… the data were analyzed using both OLS regression and Seemingly Unrelated Regression. Contrary to expectations, these migration streams appear unaffected by the 1968 immigration policy change; rather the results indicated that the strongest and most consistent of determinant of the …

Trade, migration, poverty and inequality: A global perspective
… trade and migration flows data within a seemingly unrelated regression gravity model framework. The study finds that trade and migration are complements, which means that larger migration flows are associated with higher trade flows, and vice versa. Although these results do not …

A discrete-time approach for valuing real options with underlying mean-reverting stochastic processes
… analysis techniques such as Kalman filtering and seemingly unrelated regression are used. These different techniques are empirically tested to evaluate differences in the estimates and assess the tradeoffs in computational requirements. To validate the binomial model, results are compared to those …

A Spatial Econometric Analysis of Selected Local Labour Market Outcomes in New Zealand
… labour force. This is investigated using spatial seemingly unrelated regression. The results indicate that three factors in particular matter in the determination of labour market participation and social security benefit uptake: the age structure of the population, the past performance of the …

Performance and JSE listing of selected South African hospital operators
… Insured Population, respectively. The specified regression equation was expanded to include simultaneous equations for the proxies of hospital performance. From this system of simultaneous equations, the study estimated the panel regression model using Seemingly Unrelated Regression (SUR). The …

Househood demand for comodities in Zambia: an Emperical assessment in context of food insecurity
… system was estimated by nonlinear Iterated Seemingly Unrelated Regression (ITSUR) technique using EVIEWS econometric package. The results showed that maize meal, fish/kapenta, fruit/vegetables were inelastic and meat was elastic. The result also showered that meat was a luxury commodity. The …

Beyond Firm Boundaries: Exploring The Interdependence Between Supply Chain Partners
… dataset of 2861 buyer-supplier dyads and Seemingly Unrelated Regression (SUR), we jointly evaluate the extent to which buyer`s bargaining power is simultaneously associated with improved buyer performance and diminished supplier performance. We find that buyer`s bargaining power is …
