Methods of interpreting error estimates for grayscale image reconstructions

Aaron Defazio, Mark Tygert

One representation of possible errors in a grayscale image reconstruction is as another grayscale image estimating potentially worrisome differences between the reconstruction and…

An implementation of a randomized algorithm for principal component analysis

Arthur Szlam, Yuval Kluger, Mark Tygert

Recent years have witnessed intense development of randomized methods for low-rank approximation. These methods target principal component analysis (PCA) and the calculation of tru…

Computing the asymptotic power of a Euclidean-distance test for goodness-of-fit

William Perkins, Gary Simon, Mark Tygert

A natural (yet unconventional) test for goodness-of-fit measures the discrepancy between the model and empirical distributions via their Euclidean distance (or, equivalently, via i…

Computing the confidence levels for a root-mean-square test of goodness-of-fit, II

William Perkins, Mark Tygert, Rachel Ward

This paper extends our earlier article, "Computing the confidence levels for a root-mean-square test of goodness-of-fit;" unlike in the earlier article, the models in the present p…

An algorithm for the principal component analysis of large data sets

Nathan Halko, Per-Gunnar Martinsson, Yoel Shkolnisky +1

Recently popularized randomized methods for principal component analysis (PCA) efficiently and reliably produce nearly optimal accuracy --- even on parallel processors --- unlike t…

Computing the confidence levels for a root-mean-square test of goodness-of-fit

William Perkins, Mark Tygert, Rachel Ward

The classic chi-squared statistic for testing goodness-of-fit has long been a cornerstone of modern statistical practice. The statistic consists of a sum in which each summand invo…
