Two modeling strategies for empirical Bayes estimation
f-modeling g-modeling Bayes rule in terms of f
2015/8/20
Empirical Bayes methods use the data from parallel experiments, for instance observtions Xk N (k;1) for k = 1;2; : : : ; N, to estimate the conditional distributions kjXk.
There are two main estima...
The importance of distinct modeling strategies for gene and gene-specific treatment effects in hierarchical models for microarray data
Diffierential expression EM algorithm hierarchical models random effects uncertainty
2012/11/23
When analyzing microarray data, hierarchical models are often used to share information across genes when estimating means and variances or identifying differential expression. Many methods utilize so...
Geometric Ergodicity & Scanning Strategies For Two-Component Gibbs Samplers
Geometric Ergodicity Scanning Strategies Two-Component Gibbs Samplers
2012/11/23
In any Markov chain Monte Carlo analysis, rapid convergence of the chain to its target probability distribution is of practical and theoretical importance. A chain that converges at a geometric rate i...
Equilibrium balking strategies in the single server Markovian queue with catastrophes
Queueing, Catastrophes Balking Nash equilibrium strategies Social optimization
2011/9/2
Abstract: We consider a Markovian queue subject to Poisson generated catastrophes. Whenever a catastrophe occurs, all customers are forced to abandon the system, the server is rendered inoperative and...
Stability of strategies in payoff-driven evolutionary games on networks
networks payoff-driven evolutionary games strategies
2011/7/6
We consider a network of coupled agents playing the Prisoner's Dilemma game, in which players are allowed to pick a strategy in the interval [0,1], with 0 corresponding to defection, 1 to cooperation,...
Synergy in spreading processes: from exploitative to explorative foraging strategies
synergistic effects bond-percolation epidemiological model
2011/7/7
An epidemiological model which incorporates synergistic effects that allow the infectivity and/or susceptibility of hosts to be dependent on the number of infected neighbours is proposed. Constructive...
Higher-dimensional normalisation strategies for acyclicity
Higher-dimensional normalisation strategies acyclicity
2010/11/9
We introduce acyclic track polygraphs, a notion of complete categorical cellular models for small categories: they are polygraphs containing generators, with additional invertible cells for relations ...
Transmission Strategies in Multiple Access Fading Channels with Statistical QoS Constraints
Transmission Strategies Multiple Access Fading Channels Statistical QoS Constraints
2010/12/8
Effective capacity, which provides the maximum constant arrival rate that a given service process can support while satisfying statistical delay constraints, is analyzed in a multiuser scenario. In pa...
Efficient Information Aggregation Strategies for Distributed Control and Signal Processing
Efficient Information Aggregation Strategies Distributed Control Signal Processing
2010/12/14
This thesis will be concerned with distributed control and coordination of networks consisting of multiple, potentially mobile, agents. This is motivated mainly by the emergence of large scale network...
Optimal stirring strategies for passive scalar mixing
Optimal stirring strategies passive scalar mixing
2010/12/15
We address the challenge of optimal incompressible stirring to mix an initially inhomogeneous
distribution of passive tracers. As a quantitative measure of mixing we adopt the H1 norm of th...
Statistical identification with hidden Markov models of large order splitting strategies in an equity market
Statistical identification hidden Markov models order splitting strategies
2010/4/27
Large trades in a financial market are usually split into smaller parts and traded incrementally over extended periods of time. We address these large trades as hidden orders. In order to identify and...
Vaccination Strategies of Population Groups with Distinct Perceived Probabilities of Infection
Vaccination strategies games Population dynamics Dynamical systems and games
2010/1/22
Previous modelling studies have formalized the "Tragedy of the Commons" that can occur under a voluntary vaccination policy, when there is a significant payoff not to vaccinate under conditions where ...
A new mathematical model for a redundancy allocation problem with mixing components redundant and choice of redundancy strategies
Redundancy Allocation Problem Reliability Series-Parallel Systems
2010/9/16
This paper presents a new mathematical model of a redundancy allocation problem with mixing components redundant in subsystems of a series-parallel system when the redundancy strategy can be chosen fo...
