11. Bayesian uncertainty analysis under prior ignorance of the measurand vs. analysis using the Supplement to the Guide: A comparison
Published: 2/17/2009
Authors: Blaza Toman, Clemens Elster
Abstract: A recent supplement to the GUM (GUM S1) is compared with a Bayesian analysis in terms of a particular task of data analysis, one where no prior knowledge of the measurand is presumed. For the Bayesian analysis, an improper prior density on the measur ...

12. Three Statistical Paradigms for The Assessment and Interpretation of Measurement Uncertainty
Published: 1/12/2009
Authors: William F Guthrie, Hung-Kung Liu, Andrew L Rukhin, Blaza Toman, Chih-Ming Wang, Nien F Zhang
Abstract: The goals of this chapter are to present different approaches to uncertainty assessment from a statistical point of view and to relate them to the methods that are currently being used in metrology or are being developed within the metrology communit ...

13. Calibration and Uncertainty Analysis of Predictions from Computational Models
Published: 8/18/2008
Author: Blaza Toman
Abstract: Computer experiments, that is, experiments performed using a mathematical model of a physical or chemical process implemented using a computer simulation are especially useful when extensive physical experimentation is either impossible or too expens ...

14. Model Based Uncertainty Analysis in Inter-Laboratory Studies
Published: 6/23/2008
Authors: Blaza Toman, Antonio M Possolo
Abstract: Statistical analysis of key comparison and inter-laboratory experiments is required to produce an estimate of the measurand called a reference value and further, measures of equivalence of the participating laboratories. Methods of estimation of the ...

15. Uncertainty Due to Finite Resolution Measurements
Published: 5/1/2008
Authors: Steven David Phillips, Blaza Toman, William Tyler Estler

16. Assessment of measurement uncertainty via observation equations
Published: 12/3/2007
Authors: Antonio M Possolo, Blaza Toman
Abstract: According to the Guide to the Expression of Uncertainty in Measurement, measurement uncertainty is assessed by computational propagation of error based on a measurement equation that expresses the measurand as a known function of input variables. How ...

17. Statistics in Metrology: International Key Comparisons and Interlaboratory Studies
Published: 7/10/2007
Authors: N Sedransk, Andrew L Rukhin, Blaza Toman
Abstract: An approach to the analysis of key comparisons data is proposed using a model taken from meta-analysis metrology. Under the assumption of Gaussian distributions and equivalent qualification of all participating laboratories the analysis of data fro ...

18. Statistical Interpretation of Key Comparison Degrees of Equivalence Based on Distributions of Belief
Published: 4/2/2007
Author: Blaza Toman
Abstract: In a Key Comparison experiment, the Mutual Recognition Arrangement (MRA) requires the calculation of the Degrees of Equivalence (DoE) and the accompanying measures of uncertainty. Unilateral DoEs have been defined as a difference between a laboratory ...

19. Comments on 'Bayesian evaluation of comparison data' by Ignacio Lira
Published: 1/1/2007
Authors: Raghu N Kacker, Blaza Toman
Abstract: A recent paper by Ignacio Lira in Metrologia 43 (2006) S231-S234 addresses a well-known problem in combining information from interlaboratory evaluations. Lira presents an expression, which he claims to be the kernel of a Bayesian posterior probabili ...
