11. Uncertainty Analysis for Vector Measurands Using Fiducial Inference
Published: 1/1/2006
Authors: Chih-Ming Wang, Hariharan K Iyer
Abstract: This paper presents a method for constructing uncertainty regions for a vector measurand in the presence of both type-A and type-B errors. The method is based on the principle of fiducial inference and generally requires a Monte Carlo approach for co ...

12. Propagation of Uncertainties in Measurements Using Structural Inference
Published: 3/21/2005
Authors: Hariharan K Iyer, Chih-Ming Wang
Abstract: The ISO Guide to the Expression of Uncertainty in Measurement (GUM) recommends the use of a first-order Taylor series expansion for propagating errors and uncertainties. The GUM also permits the use of other analytical or numerical methods when the ...

13. Detection of influential observation in the determination of the weighted-mean KCRV
Published: 1/1/2005
Authors: Chih-Ming Wang, Hariharan K Iyer
Abstract: Since the signing of the Mutual Recognition Arrangement, National Metrology Institutes (NMI) have carried out many key comparisons in a wide range of metrological areas to establish the equivalence of their measurement standards. The determination of ...

14. On Higher Order Corrections for Propagating Uncertainties
Published: 1/1/2005
Authors: Chih-Ming Wang, Hariharan K Iyer
Abstract: The ISO Guide to the Expression of Uncertainty in Measurement (GUM) recommends the use of a first-order Taylor series expansion for propagating errors and uncertainties. The GUM also suggests the use of a second-order Taylor series approximation for ...

15. Propagation of uncertainties in measurements using generalized influence
Published: 1/1/2005
Authors: Hariharan K Iyer, Chih-Ming Wang
Abstract: The ISO Guide to the Expression of Uncertainty in Measurement (GUM) recommends the use of a first- order Taylor series expansion for propagating errors and uncertainties. The GUM also permits the use of "other analytical or numerical methods" when th ...

16. Models and Confidence Intervals for True Values in Interlaboratory Trials
Published: 12/6/2004
Authors: Hariharan K Iyer, Chih-Ming Wang, T Mathew
Abstract: We consider the one-way random effects model with unequal sample sizes and heterogeneous variances. Using the method of generalized confidence intervals, we develop a new confidence interval procedure for the mean. Additionally, we investigate two ...

17. Some Statistical Methods Applicable to Key Comparisons Studies
Published: Date unknown
Authors: Hariharan K Iyer, Chih-Ming Wang, Dominic F. (Dominic F.) Vecchia
Abstract: Results of International Key Comparisons of National Measurement Standards provide the technical basis for the Mutual Recognition Arrangement formulated by Le Comite International des Poids et Mesures. With many key comparisons already completed and ...
