Modeling Security and Cooperation in Wireless Networks Using Game Theory

Kamhoua, Charles A. K. - 2011

misbehavior resolution protocols for ad hoc networked devices. Game theory was used to analyze strategic interaction among … system operation feasible. Motivated by the versatile nature of evolutionary game theory, the assumption of a rational node … malicious attacks. Therefore, using game theory and evolutionary game theory, a mathematical framework has been developed that …

Likelihood-based estimation of latent generalised ARCH structures

Fiorentini, Gabriele; Sentana, Enrique; Shephard, Neil - 2004

GARCH models are commonly used as latent processes in econometrics, financial economics, and macroeconomics. Yet no exact likelihood analysis of these models has been provided so far. In this paper we outline the issues and suggest a Markov chain Monte Carlo algorithm which allows the...

Analysis of high dimensional multivariate stochastic volatility models

Chib, Siddhartha; Nardari, Federico; Shephard, Neil - 2006

This paper is concerned with the Bayesian estimation and comparison of flexible, high dimensional multivariate time series models with time varying correlations. The model proposed and considered here combines features of the classical factor model with that of the heavy tailed univariate...

Trip-Level Analysis of Efficiency Changes in Oregon's Deepwater Trawl Fishery

Tomberlin, David; Holloway, Garth J. - 2007

In 2003, an industry-financed, government-administered buyback of trawl fishing permits and vessels took place on the US West Coast, resulting in the retirement of about one-third of the limited-entry trawl fleet. The lack of cost data in this fishery precludes an analysis of how the buyback has...

Zero Tolerance Ecology: Improving Ecological Inference By Modelling the Source of Zero Observations

Martin, Tara G.; Wintle, Brendan A.; Rhodes, Jonathan R.; … - 2005

A common feature of ecological datasets is their tendency to contain many zero values. Statistical inference based on such data is likely to be inefficient or wrong unless careful thought is given to how these zeros arose and how best to model them. In this paper, we propose a framework for...

Labor market policies in an equilibrium matching model with heterogeneous agents and on-the-job search

Stavrunova, Olena - 2007

This dissertation quantitatively evaluates selected labor market policies in a search-matching model with skill heterogeneity where high-skilled workers can take temporary jobs with skill requirements below their skill levels. The joint posterior distribution of structural parameters of the...

Time-varying covariates and semi-parametric regression in capture-recapture: an adaptive spline approach

Bonner, SJ; Thomson, DL; Schwarz, CJ - 2009

Advances in capture–recapture methodology have allowed the inclusion of continuous, time-dependent individual-covariates as predictors of survival and capture probabilities. The problem posed by these covariates is that they are only observed for an individual when that individual is captured....

Three Essays on Bayesian Factor Models

Piatek, Rémi - 2010

The present dissertation consists of three stand-alone research papers that all deal with factor models from a Bayesian perspective, both in a theoretical and an empirical setup. More precisely, the thesis is organized in a progressive way as follows: Chapter 1 briefly presents the general...
