The purpose of this study is designing a model based on Tobit regression, DEA, Artificial Neural Network, Genetic Algorithm and Particle Swarm Optimization to evaluate the efficiency and also benchmarking the efficient and inefficient units. This model has three stages, and it uses the data envelopment analysis combined model with neural network, optimized by genetic algorithm, to evaluate the ...

The nonlinear fixed effects model has two shortcomings, one practical, one methodological. The practical obstacle relates to the difficulty of estimating nonlinear models with possibly thousands of dummy variable coefficients. In fact, in many models of interest to practitioners, estimation of the fixed effects model is feasible even in panels with very large numbers of groups. The result, thou...

Abstract In this paper, the industrial green efficiency of each province is measured by non-radial SBM model, and then makes a tobit regression environmental regulations with efficiency. Finally, heterogeneity region are analyzed.

This paper analyzed the impact of domestic violence on HIV vulnerability using the 2008 Demographic and Health Survey (DHS) data. Fuzzy set method was used to construct indices of HIV vulnerability and its correlates were determined by Tobit regression. It was found that among the selected HIV vulnerability attributes, the number of other wives contributed the most (10.30 percent) to HIV vulner...

This paper examines the impact of family size on household saving. We first study a theoretical life-cycle model that includes finite lifetimes and saving for retirement and in which parents care about the consumption of their dependent children. The model implies a negative relationship between the number of dependent children in the family and the household’s saving rate. Then, we test the mo...

This paper aims to evaluate the operating efficiency of e-market for exploring the efficiency-oriented critical drivers on the development of e-market. A hybrid approach consisting of data envelopment analysis (DEA) and bootstrapped Tobit regression analysis is adopted. The efficiency of forty-three emarkets is investigated with respect to their respective overall efficiency, technical efficien...

PURPOSE To map health outcome related variables from a national register, not part of any validated instrument, with EQ-5D weights among stroke patients. METHODS We used two cross-sectional data sets including patient characteristics, outcome variables and EQ-5D weights from the national Swedish stroke register. Three regression techniques were used on the estimation set (n=272): ordinary lea...

INTERVAL ESTIMATION OF EXCESS RISK RELATED EFFECTIVE DOSES IN TOBIT MODELS by Jia Wang ADVISOR: Professor Nan Lin December 2009 Saint Louis, Missouri In this thesis we consider interval estimation of excess risk related effective dose (ERED) in dose-response studies using tobit model. Let P (x) be the probability of response at dose level x. Considering the background probability P (0), excess ...

BACKGROUND Modulation of endogenous epoxide levels by soluble epoxide hydrolase (sEH) in the endothelium represents an important mechanism in the regulation of cardiovascular function. We examined the relationship between a common, functional polymorphism of the human sEH gene and coronary artery calcification (CAC) in young, largely asymptomatic African-American and non-Hispanic white subjects...
