Semiparametric quasilikelihood and variance function estimation in measurement error models
(Elsevier, 1993-07)
We consider a quasilikelihood/variance function model when a predictor X is measured with error and a surrogate W is observed. When in addition to a primary data set containing (Y,W) a validation data set exists for which ...
Stock market crash and expectations of American households
(John Wiley & Sons, Ltd., 2011-04)
This paper utilizes data on subjective probabilities to study the impact of the stock market crash of 2008 on households' expectations about the returns on the stock market index. We use data from the Health and Retirement ...
System Design and Implementation of a National Image Registry for Orthopaedic Oncology Image Management, Research and Teaching
(Kluwer Academic Publishers; Springer Science+Business Media, 2003-12)
Orthopaedic oncology is highly dependent on imaging studies to diagnose and treat patients. However, many types of bone tumors are rare creating a lack of teaching and research cases. We have developed a system to locally ...
The allocation of household income to food consumption
(Elsevier, 1976-05)
Low-income households - those toward which various income supplement programs are aimed - not only spend a large share of their incomes on food, but exhibit a higher income elasticity of demand for food than does the rest ...
Semiparametric instrumental variable estimation of simultaneous equation sample selection models
(Elsevier, 1994-08)
The identification and estimation of a semiparametric simultaneous equation model with selectivity have been considered. The identification of structural parameters from reduced form parameters in the semiparametric model ...
Some Problems in Stochastic Control Theory Related to Inventory Management and Coarsening.
(2014)
In this dissertation, we study two stochastic control problems arising from inventory management and coarsening.
First, we study a stochastic production/inventory system with a finite production capacity and random demand. ...
Semiparametric two-stage estimation of sample selection models subject to Tobit-type selection rules
(Elsevier, 1994-04)
A semiparametric two-stage estimation method is proposed for the estimation of sample selection models which are subject to Tobit-type selection rules. With randomization restrictions on the disturbances of the model, all ...
Optimal process adjustment by integrating production data and design of experiments
(John Wiley & Sons, Ltd., 2011-04)
This paper proposes a method to improve the process model estimation based on limited experimental data by making use of abundant production data and to achieve the optimal process adjustment based on the improved process ...
Expected move request waiting times in single-device, polling-based material handling systems
(Kluwer Academic Publishers; Springer Science+Business Media, 2001-01)
We present an analytical approach to approximate the expected waiting times of move requests (customers) served by a single handling device (server) that operates according to the First-Encountered-First-Served (FEFS) rule, ...
A reexamination of the distance-based facility layout problem
(Kluwer Academic Publishers; Chapman and Hall ; Springer Science+Business Media, 1997-07)
In this paper we qualitatively and numerically compare basic modeling approaches to the distance-based facility layout problem and the types of result obtained from them. In the process we observe that when the facility ...
