Statistical study of asymmetry in cell lineage data

Authors: Benoîte de Saporta, Anne Gégout Petit, Laurence Marsalle

arXiv

A rigorous methodology is proposed to study cell division data consisting in several observed genealogical trees of possibly different shapes. The procedure takes into account missing observations, da...

Identification of gene pathways implicated in Alzheimer's disease using longitudinal imaging phenotypes with sparse regression

Authors: Matt Silver, Eva Janousova, Xue Hua, Paul M. Thompson, Giovanni Montana

arXiv

We present a new method for the detection of gene pathways associated with a multivariate quantitative trait, and use it to identify causal pathways associated with an imaging endophenotype characteri...

Energy cost reduction in the synchronization of a pair of nonidentical coupled Hindmarsh-Rose neurons

Authors: A. Moujahid, A. D'Anjou, F. J. Torrealdea, C. Sarasola

arXiv

Many biological processes involve synchronization between nonequivalent systems, i.e, systems where the difference is limited to a rather small parameter mismatch. The maintenance of the synchronized...

A Log-Linear Graphical Model for Inferring Genetic Networks from High-Throughput Sequencing Data

Authors: Genevera I. Allen, Zhandong Liu

arXiv

Gaussian graphical models are often used to infer gene networks based on microarray expression data. Many scientists, however, have begun using high-throughput sequencing technologies to measure gene...

Kernel discriminant analysis and clustering with parsimonious Gaussian process models

Authors: Charles Bouveyron, Stéphane Girard, Mathieu Fauvel

arXiv

This work presents a family of parsimonious Gaussian process models which allow to build, from a finite sample, a model-based classifier in an infinite dimensional space. The proposed parsimonious mod...

Local asymptotically optimal test in ARCH model

Authors: Tewfik Lounis

arXiv

This work is an extension in Arch models of the theorem of S.Y. Hwang and I.V. Basawa Hwang and Basawa (2001) which was used before in nonlinear time series contiguous to AR(1) processes. Our results...

Modeling and forecasting daily average PM$_{10}$ concentrations by a seasonal ARFIMA model with volatility

Authors: V. A. Reisen, A. J. Q Sarnaglia, N. C. Reis, C. Lévy-Leduc, J. M. Santos

arXiv

This paper considers the possibility that the daily average Particulate Matter (PM$_{10}$) concentration is a seasonal fractionally integrated process with time-dependent variance (volatility). In thi...

Nonparametric ROC Summary Statistics for Correlated Diagnostic Marker Data

Authors: Liansheng Larry Tang, Aiyi Liu, Zhen Chen, Enrique F. Schisterman, Bo Zhang, Zhuang Miao

arXiv

We propose efficient nonparametric statistics to compare medical imaging modalities in multi-reader multi-test data and to compare markers in longitudinal ROC data. The proposed methods are based on t...

Frequency decoding of periodically timed action potentials through distinct activity patterns in a random neural network

Authors: Tobias Reichenbach, A. J. Hudspeth

arXiv

Frequency discrimination is a fundamental task of the auditory system. The mammalian inner ear, or cochlea, provides a place code in which different frequencies are detected at different spatial locat...

Soil Data Analysis Using Classification Techniques and Soil Attribute Prediction

Authors: Jay Gholap, Anurag Ingole, Jayesh Gohil, Shailesh Gargade, Vahida Attar

arXiv

Agricultural research has been profited by technical advances such as automation, data mining. Today, data mining is used in a vast areas and many off-the-shelf data mining system products and domain...

Optimal feature selection for sparse linear discriminant analysis and its applications in gene expression data

Authors: Cheng Wang, Longbing Cao, Baiqi Miao

arXiv

This work studies the theoretical rules of feature selection in linear discriminant analysis (LDA), and a new feature selection method is proposed for sparse linear discriminant analysis. An $l_1$ min...

How to analyse percentile impact data meaningfully in bibliometrics: The statistical analysis of distributions, percentile rank classes and top-cited papers

Authors: Lutz Bornmann

arXiv

According to current research in bibliometrics, percentiles (or percentile rank classes) are the most suitable method for normalising the citation counts of individual publications in terms of the sub...

Adjusted Plus-Minus for NHL Players using Ridge Regression with Goals, Shots, Fenwick, and Corsi

Authors: Brian Macdonald

arXiv

Regression-based adjusted plus-minus statistics were developed in basketball and have recently come to hockey. The purpose of these statistics is to provide an estimate of each player's contribution t...

Nearly extensive sequential memory lifetime achieved by coupled nonlinear neurons

Authors: Taro Toyoizumi

arXiv

Many cognitive processes rely on the ability of the brain to hold sequences of events in short-term memory. Recent studies have revealed that such memory can be read out from the transient dynamics of...

Meta-models for structural reliability and uncertainty quantification

Authors: Bruno Sudret

arXiv

A meta-model (or a surrogate model) is the modern name for what was traditionally called a response surface. It is intended to mimic the behaviour of a computational model M (e.g. a finite element mod...
