- A Likelihood Approach to Estimating Market Equilibrium Models
- This paper develops a new likelihood-based method for the simultaneous estimation of structural demand-and-supply models for markets with differentiated products. This paper specifies an individual-level discrete choice model of demand and derives the supply side assuming manufacturers compete in prices. The proposed estimation method considers price endogeneity through simultaneous estimation...

- Refinement and Validation of In-Situ Parameter Estimation Models
- This paper discusses the refinement and validation of in-Situ parameter estimation models. The validation of the parameter estimation method must be based on high-quality input data in order to increase the confidence in the parameter estimation model. This is to be done using a medium-scale borehole apparatus that was constructed...

- Supreme Court approves IRS method for employer FICA on tips
- May the IRS use an aggregate estimation method to determine unreported tips and then assess employer FICA taxes on the estimated unreported amounts? According to a recent Supreme Court decision in U.S. v. Flor D'Italia [536 U.S. - (2002), 2002-1 USTC 50,4591, the answer is yes. The decision settles the...

- Variance estimation for survey data with composite imputation and nonnegligible sampling fractions.
- An estimation method based on variance decomposition is considered for Horvitz-Thompson-type estimated totals based on survey data with composite imputation and nonnegligible sampling fractions. The proposed approach is applicable to complicated cases where a composite of certain deterministic and/or random imputation techniques is utilized, including the use of imputed values...

- Measurement and Estimation of Credit Migration Matrices
- Credit migration matrices are cardinal inputs to many risk management applications. Their accurate estimation is therefore critical. One explores three approaches, cohort and two variants of duration - time homogeneous and non-homogeneous - and the resulting differences, both statistically through matrix norms and economically through credit portfolio and credit derivative...

- Evaluating Concentration Estimation Errors in ELISA Microarray Experiments
- This white paper presents a statistical method based on propagation of error to evaluate concentration estimation errors in the ELISA microarray process. Although propagation of error is central to this method and the focus of this paper, it is most effective only when comparable data are available. Therefore, the paper...

- Institute for Operations Research and the Management Sciences
- This paper investigates the problem of planning marketing mix in dynamic competitive markets. The authors extend the Lanchester model by incorporating interaction effects, constructing the marketing-mix algorithm that yields marketing-mix plans with strategic foresight, and developing the continuous-discrete estimation method to calibrate dynamic models of oligopoly using market data. Both...

- Generalized method of moments estimation when a parameter is on a boundary.
- This article establishes the asymptotic distributions of generalized method of moments GMM estimators when the true parameter lies on the boundary of the parameter space. The conditions allow the estimator objective function to be nonsmooth and to depend on preliminary estimators. The boundary of the parameter space may be curved...

- Bandwidth selection for indirect density estimation based on corrupted histogram data.
- A modified version of the method of unbiased risk estimation is proposed. The statistical methodology is based on formulas that use adjustments for correction factor variability applied to the generation of reconstruction histograms. It can accommodate extra-Poisson variation and reduces naturally to a new cross-validation type. Computational experiment show the...

- Latency Estimation
- Latency estimation promises to improve system performance in safety critical systems that integrate periodic and a periodic (i.e. event-triggered) traffic in several important ways. For the first time under a broad range of practical system design conditions, it can provide designers a reasonable method for analyzing how long it takes...

- The Sensitivity Of Productivity Estimates: Revisiting Three Important Debates
- Researchers interested in estimating productivity can choose from an array of methodologies, each with its strengths and weaknesses. This paper compares productivity estimates and evaluates the extent to which the conclusions from three important productivity debates in the economic development literature are sensitive to the choice of estimation method. Five...
