Higher Criticism for Detecting Sparse Heterogeneous Mixtures
Multiple Comparsions Combining Many p-values
2015/8/21
Higher Criticism, or second-level significance testing, is a multiple comparisons concept
mentioned in passing by Tukey (1976). It concerns a situation where there are many independent tests of...
Detecting the Presence of Mixing with Multiscale Maximum Likelihood
Log-concave Mixture detection
2015/8/20
A test of homogeneity tries to decide whether observations come from a single distribution or from a mixture of several distributions.
A powerful theory has been developed for the case where the comp...
A Statistical Test on Capability of SNP Microarray Detecting CNVs: A Comparison to Sequence
Statistical Test Sequence
2014/12/5
Copy number variations (CNVs) are gains and losses of DNA se-quence of a genome, which result in the abnormality of the cell or
individual. The data from single nucleotide polymorphism (SNP)
microar...
Detecting mutations in mixed sample sequencing data using empirical Bayes
Detecting mutations mixed sample sequencing data empirical Bayes
2012/11/23
We develop statistically based methods to detect single nucleotide DNA mutations in next generation sequencing data. Sequencing generates counts of the number of times each base was observed at hundre...
Detecting ends of residually finite groups in profinite completions
residually finite groups profinite completions Group Theory
2012/5/24
Let $\C$ be a variety of finite groups. We use profinite Bass--Serre theory to show that if $u:H\hookrightarrow G$ is a map of finitely generated residually $\C$ groups such that the induced map $\hat...
Detecting coherent structures using braids
topological chaos dynamical systems Lagrangian coherent structures
2011/7/5
The detection of coherent structures is an important problem in
uid dynamics,
particularly in geophysical applications. For instance, knowledge of how regions of
uid are isolated from each other...
Detecting the temporal structure of intermittent phase locking
Detecting temporal structure intermittent phase locking
2011/7/7
This study explores a method to characterize temporal structure of intermittent phase locking in oscillatory systems. When an oscillatory system is in a weakly synchronized regime away from a synchron...
Nonparametric test for detecting change in distribution with panel data
nonparametric estimation panel data process
2011/6/15
This paper considers the problem of comparing two processes with
panel data. A nonparametric test is proposed for detecting a monotone
change in the link between the two process distributions. The t...
Detecting changes in functional linear models
functional data projections weak dependence change point weak convergence
2011/6/15
We observe two sequences of curve which are connected via an integral operator. Our model includes linear models as well as autoregressive models in Hilbert spaces. We wish to test the null hypothesis...
Combinatorial Methods for Detecting Surface Subgroups in Right-Angled Artin Groups
Combinatorial Methods Surface Subgroups Right-Angled Artin Groups
2011/2/23
We give a short proof of the following theorem of Sang-hyun Kim:if A() is a right-angled Artin group with de ning graph , then A() contains a hyperbolic surface subgroup ...

Checking the Reliability of a Linear-Programming Based Approach Towards Detecting Community Structures in Networks
Checking the Reliability a Linear-Programming Based Approach Detecting Community Structure Networks
2014/6/3
We investigate the reliability of a recent approach to use parameterized linear programming for detecting community structures in networks. Using a one-parameter family of objective functions, a numbe...
