1. Statistical Analysis of Reader Measurement Variability in Nodule Sizing with CT Phantom Imaging Data
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 7879
Topic: Statistics
Published: 11/23/2012
Authors: John Lu, Charles D. Fenimore, Nicholas Petrick, Rongping Zeng, Marios A Gavrielides, David Clunie, Kristin Borradaile, Robert Ford, Hyun J. Grace Kim, Michael McNitt-Gray, Binsheng Zhao, Andrew Buckler
Abstract: RSNA has conducted a phantom quantitative imaging biomarker (QIBA) study to assess reader measurement variability of both spherical and non-spherical nodules using CT imaging. Statistical analysis of intra-reader and inter-reader variability of v ...

2. An Empirical Bayes Approach to Robust Variance Estimation: A Statistical Proposal for Quantitative Medical Image Testing
Topic: Statistics
Published: 10/23/2012
Authors: John Lu, Charles D. Fenimore
Abstract: The current standard for measuring tumor response using X-ray, CT and MRI is based on the response evaluation crite- rion in solid tumors (RECIST) which, while providing simplifications over previous (WHO) 2-D methods, stipulate four response categor ...

3. Improving optical measurement uncertainty with combined multitool metrology using a Bayesian approach
Topic: Statistics
Published: 8/30/2012
Authors: Nien F Zhang, Richard M Silver, Hui Zhou, Bryan M Barnes
Abstract: Recently, there has been significant research investigating new optical technologies for dimensional metrology of features 22 nm in critical dimension and smaller. When modeling optical measurements, a library of curves is assembled through the simul ...

4. Incorporating Attribute Value Uncertainty into Decision Analysis
Topic: Statistics
Published: 5/28/2012
Authors: Dennis D Leber, Jeffery W Herrmann
Abstract: Attribute value uncertainty is present in a decision when the consequences are characterized by uncertain estimates of the underlying, unknown true values. Attributes defined based upon measurement data, experimental data, or survey data are subject ...

5. Pivotal Methods in the Propagation of Distributions
Topic: Statistics
Published: 4/24/2012
Authors: Chih-Ming Wang, Jan Hannig, Hariharan K Iyer
Abstract: We propose a method for assigning a probability distribution to an input quantity. The distribution is used in the Monte Carlo method for uncertainty evaluation. The proposed method provides an alternative to other methods, such as the principle of m ...

6. Evaluation of Segmentation Algorithms on Cell Populations Using CDF Curves
Topic: Statistics
Published: 2/24/2012
Author: Robert Charles Hagwood
Abstract: Cell segmentation is a critical step in the analysis pipeline for most imaging cytometry experiments and the segmentation algorithm can effect the quantitative data derived from image analysis. Methods to evaluate segmentation algorithms are importan ...

7. Fiducial Prediction Intervals
Topic: Statistics
Published: 2/18/2012
Authors: Chih-Ming Wang, Jan Hannig, Hariharan K Iyer
Abstract: This paper presents an approach for constructing prediction intervals for any given distribution. The approach is based on the principle of fiducial inference. We use several examples, including the normal, binomial, gamma, and Weibull distributions, ...

8. Asymptotically Optimal Confidences for Rejecting Local Realism
Topic: Statistics
Published: 12/22/2011
Authors: Yanbao Zhang, Scott C Glancy, Emanuel H Knill
Abstract: Reliable experimental demonstrations of violations of local realism are highly desirable for fundamental tests of Quantum Mechanics. Such violations can be quantified in terms of a confidence for rejecting local realism. We propose a method for comp ...

9. Universal Low-rank Matrix Recovery from Pauli Measurements
Topic: Statistics
Published: 12/12/2011
Author: Yi-Kai Liu
Abstract: We study the problem of reconstructing an unknown matrix M of rank r and dimension d using O(rd poly log d) Pauli measurements. This has applications in quantum state tomography, and is a non- commutative analogue of a well-known problem in compress ...

10. Condensation Particle Counter Proportionality Calibration from 1 particle•cm-3 to 104 particles•cm-3
Topic: Statistics
Published: 11/29/2011
Authors: Miles Owen, George W. Mulholland, William F Guthrie
Abstract: The linearity of a condensation particle counter (CPC) (3760A, TSI, Inc.) for a monodisperse aerosol has been previously evaluated by comparison to an aerosol electrometer (AE) (Fletcher et al., 2009). The comparison of the CPC to the AE is an absolu ...
