Causality and pathway search in microarray time series experiment
MOTIVATION Interaction among time series can be explored in many ways. All the approach has the usual problem of low power and high dimensional model. Here we attempted to build a causality network among a set of time series. The causality has been established by Granger causality, and then constructing the pathway has been implemented by finding the Minimal Spanning Tree within each connected ...
متن کاملComment on causality and pathway search in microarray time series experiment
We thank Professors Nagarajan and Upreti for their interest in our paper, Mukhopadhyay and Chatterjee (2007). There, we propose using Granger causality-based pathway detection in an acyclic, homoscedastic framework for microarray time-series expressions; which are generally short-duration time series involving very large number of genes. Professors Nagarajan and Upreti point out that in the pre...
متن کاملReply to B.M. P6tscher’s comment on ‘Adaptive estimation in time series regression models’
Nearly all of Pbtscher’s comment on my 1992 paper is taken up with three accusations, each of which is wrong and easily dismissed. Potscher also finds and reports two typographical errors. As well, the reviewer of Potscher’s comment finds two typographical errors and one substantive but minor error, which I correct below. For brevity (P) refers to Potscher’s comment and (S) to my original paper...
متن کاملOn Causality Inference in Time Series
Causality discovery has been one of the core tasks in scientific research since the beginning of human scientific history. In the age of data tsunami, the task could involve millions of variables, which cannot be achieved feasibly by human. However, the causal discovery using artificial intelligence and statistical techniques in non-experimental settings faces several challenges. In this work, ...
متن کاملComment on “Reply to Comment on Time-dependent Quasi-Hermitian Hamiltonians and the Unitary Quantum Evolution”
I point out that if one defines the operator UR(t) as done by M. Znojil in his reply [arXiv:0711.0514v1] to my comment [arXiv:0711.0137v1] and also accepts the validity of the defining relation of UR(t) as given in his paper [arXiv:0710.5653v1], one finds that the time-evolution of the associated quantum system is not governed by the Schrödinger equation for the Hamiltonian operator H but an op...
