A model selection approach to genome wide association studies
Genome wide association Multiple testing Linear regression,
2010/10/14
For the vast majority of genome wide association studies (GWAS) published so far, statistical analysis was performed by testing markers individually. In this article we present some elementary statis...
Happy places or happy people?A multi-level modelling approach to the analysis of happiness and well-being
well-being multi-level modelling random effects combining data
2010/4/30
This paper aims to enhance our understanding of substantive questions regarding self-reported
happiness and well-being through the specification and use of multi-level models. To date, there have bee...
Finite Element Model Updating Using Bayesian Approach
Bayesian Maximum-likelihood finite element updating
2010/4/29
This paper compares the Maximum-likelihood method and Bayesian method for finite element model updating.The Maximum-likelihood method was implemented using genetic algorithm while the Bayesian method ...
A Bayesian Hierarchical Modeling Approach to Dietary Assessment via Food Frequency
Bayesian Hierarchical Modeling Approach Dietary Assessment Food Frequency
2010/4/26
Previous likelihood-based linear modeling of nutritional data has been limited by the availability of software that allows flexible error structures in the data. We demonstrate the use of a Bayesian m...
Extending The Range of Application of Permutation Tests：the Expected Permutation p-value Approach
Range Application Permutation Tests Expected Permutation p-value Approach
2010/3/11
The limitation of permutation tests is that they assume exchangeability.
It is shown that in generalized linear models one can construct permutation
tests from score statistics in particular cases. ...
Our article is concerned with adaptive sampling schemes for Bayesian inference that
update the proposal densities using previous iterates. We introduce a copula based
proposal density which is made ...
Random walks-a sequential approach
Control chart nonparametric smoothing sequential analysis unit roots weighted partial sum process
2010/3/9
In this paper sequential monitoring schemes to detect nonparametric drifts
are studied for the random walk case. The procedure is based on a kernel smoother. As
a by-product we obtain the asymptotic...
A martingale approach to continuous time marginal structural models
martingale approach continuous time marginal structural models
2010/3/17
Marginal structural models were introduced in order to provide
estimates of causal effects from interventions based on observational studies
in epidemiological research. We present a variant of the ...
A D.C. Programming Approach to the Sparse Generalized Eigenvalue Problem
Generalized eigenvalue problem Principal component analysis Canonicalcorrelation analysis Fisher discriminant analysis
2010/3/17
In this paper, we consider the sparse eigenvalue problem wherein the goal is to obtain a
sparse solution to the generalized eigenvalue problem. We achieve this by constraining the
cardinality of the...

Best unbiased linear estimation, a coordinate free approach。
A Bayesian Approach to Estimating the Long Memory Parameter
Bayesian model averaging FEXP hierarchical Bayes long-range dependence Spectral density
2009/9/24
We develop a Bayesian procedure for analyzing stationary long-range
dependent processes.Specically,we consider the fractional exponential model
(FEXP)to estimate the memory parameter of a stationary...
Parameter Estimation in Continuous Time Markov Switching Models: A Semi-Continuous Markov Chain Monte Carlo Approach
Bayesian inference data augmentation hidden Markov model
2009/9/24
In this paper,we combine useful aspects of both approaches.On the one hand,we are inspired by the discretization, where filtering for the state process is possible,on the other hand,we
catch attracti...
A probabilistic approach to the reduite in optimal stopping
A probabilistic approach the reduite in optimal stopping
2009/9/23
In this work the approach to the reduite is made in
a simple and unified way. More precisely, we use the same probabilistic
technique to study the optimal stopping problem associated with
the redui...
Dynamic and Structural Features of Intifada Violence: A Markov Process Approach
Bayesian conjugate prior Israeli-Palestinian conict marginal likelihood
2009/9/22
This paper analyzes the daily incidence of violence during the Second
Intifada. We compare several alternative statistical models with dierent dynamic
and structural stability characteristics while ...
