Mathematical Modeling and Simulation of the Dehydrogenation of Ethyl Benzene to Form Styrene Using Steady-State Fixed Bed Reactor

open access: yesTikrit Journal of Engineering Sciences, 2013
In this research, two models are developed to simulate the steady state fixed bed reactor used for styrene production by ethylbenzene dehydrogenation. The first is one-dimensional model, considered axial gradient only while the second is two-dimensional ...

The Maximum Likelihood Stage Least Squares Estimator in the Nonlinear Simultaneous Equations Model [PDF]

open access: yes
The consistency and the asymptotic normality of the maximum likelihood estimator in the general nonlinear simultaneous equation model are proved. It is shown that the proof depends on the assumption of normality unlike in the linear simultaneous equation

The Error of Prediction for a Simultaneous Equation Model

open access: yes
One of the most important functions of a simultaneous equation model is prediction the values of endogenous variables given the values of the predetermined variables and a lot of work has been done to estimate the accuracy of such predictions. Hooper and

"A New Light from Old Wisdoms : Alternative Estimation Methods of Simultaneous Equations with Possibly Many Instruments" [PDF]

open access: yes
We compare four dffierent estimation methods for a coefficient of a linear structural equation with instrumental variables. As the classical methods we consider the limited information maximum likelihood (LIML) estimator and the two-stage least squares ...

SIMULTANEITY OF TECHNOLOGY ADOPTION AND PRODUCTIVITY

open access: yes
A simultaneous equation generalized probit model is estimated to determine factors affecting technology adoption by California dairy farmers. Since productivity and technology choice are jointly determined, a single-equation approach to determine whether

Endogeneity in quantile regression models: a control function approach [PDF]

open access: yes
This paper considers a linear triangular simultaneous equations model with conditional quantile restrictions. The paper adjusts for endogeneity by adopting a control function approach and presents a simple two-step estimator that exploits the partially ...

A model of growth and finance: FIML estimates for India

open access: yes
Many empirical works addressed the nature of the relationship between economic growth and financial developments. Although these studies concede that they are interdependent, they have used single equations methods for estimation.
