31. 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 ...

32. Detecting differential expression in RNA-sequence data using quasi-likelihood with shrunken dispersion estimates
Topic: Statistics
Published: 10/12/2012
Author: Steven P Lund
Abstract: Next generation sequencing technology provides a powerful tool for measuring gene expression (mRNA) levels in the form of RNA-sequence data. Method development for identifying differentially expressed (DE) genes from RNA-seq data, which frequently in ...

33. A Bayesian Approach to the Analysis of Split-Plot Product Arrays and Optimization in Robust Parameter Design
Topic: Statistics
Published: 10/4/2012
Author: Adam L Pintar
Abstract: Many robust parameter design (RPD) studies involve a split-plot randomization structure and to obtain valid inferences in the analysis, it is essential to account for the design induced correlation structure. Bayesian methods are appealing for these ...

34. Bayesian Estimation of Reliability for Batches of High Reliability Single Use Parts
Topic: Statistics
Published: 9/24/2012
Author: Adam L Pintar
Abstract: When batches of critical, very high reliability single use parts are being produced, rigorous testing is often required to qualify the parts and allow them to be used by the customer. Frequentist and Bayesian approaches are described for predicting ...

35. Gradient-based stopping rules for maximum-likelihood quantum-state tomography
Topic: Statistics
Published: 9/18/2012
Authors: Scott C Glancy, Emanuel H Knill, Mark Girard
Abstract: When performing maximum likelihood quantum state tomography, one must find the quantum state that maximizes the likelihood for observed measurements on identically prepared systems, all having that quantum state. This optimization is usually perform ...

36. Preface
Topic: Statistics
Published: 9/2/2012
Authors: Andrew M Dienstfrey, Ronald F Boisvert

37. 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 H. 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 ...

38. Simultaneous Estimation and Reduction of Nonconformity in Interlaboratory Studies
Topic: Statistics
Published: 8/8/2012
Authors: Andrew L Rukhin, William E Strawderman
Abstract: Several procedures designed to reduce nonconformity in interlaboratory studies by shrinking data toward a consensus weighted mean are suggested. Some of them are shown to have a smaller quadratic risk than the vector sample mean. Shrinkage toward a w ...

39. Estimating heterogeneity variance in meta-analysis
Topic: Statistics
Published: 8/6/2012
Author: Andrew L Rukhin
Abstract: Several new estimators of the between-study variability in a heterogeneous random effects meta-analysis model are derived. One of them can be interpreted as the empirical Bayes procedure for a diffuse prior with the given prior mean. Another is th ...

40. Conformance of Image Features to Classifier Assumptions
Topic: Statistics
Published: 7/27/2012
Authors: Julien Marc Amelot, Peter Bajcsy, Mary C Brady
Abstract: Cell measurements are derived frequently from the results of pixel classification and contiguous region segmentation of microscopy images. Image segmentation is accomplished by classifying image pixels based on high dimensional image features com ...
