Correlation analysis of enzymatic reaction of a single protein molecule
Autocorrelation continuous time Markov chain fluorescence intensity Michaelis-Mente nmodel stochastic network model single-molecule experiment turnover time
2012/11/23
New advances in nano sciences open the door for scientists to study biological processes on a microscopic molecule-by-molecule basis. Recent single-molecule biophysical experiments on enzyme systems, ...
Functional dynamic factor models with application to yield curve forecasting
Functional data analysis expectation maximization algorithm natural cubic splines cross-validation roughness penalty
2012/11/23
Accurate forecasting of zero coupon bond yields for a continuum of maturities is paramount to bond portfolio management and derivative security pricing. Yet a universal model for yield curve forecasti...
Matching markers and unlabeled configurations in protein gels
Electrophoresis shape Western Blots.
2012/11/23
Unlabeled shape analysis is a rapidly emerging and challenging area of statistics. This has been driven by various novel applications in bioinformatics. We consider here the situation where two config...
People born in the Middle East but residing in the Netherlands: Invariant population size estimates and the role of active and passive covariates
Population size estimation capture-Crecapture collapsbility multiple record-systems estimation missing data structural zeros
2012/11/23
Including covariates in loglinear models of population registers improves population size estimates for two reasons. First, it is possible to take heterogeneity of inclusion probabilities over the lev...
Accounting for spatially varying directional effects in spatial covariance structures
Gaussian processes non-stationarity process convolution projection
2012/11/23
Wind direction plays an important role in the spread of pollutant levels over a geographical region. We discuss how to include wind directional information in the covariance function of spatial models...
On Simulations from the Two-Parameter Poisson-Dirichlet Process and the Normalized Inverse-Gaussian Process
Dirichlet process Nonparametric Bayesian inference Normalized inverse-Gaussian process Simulation Stable law process Stick-breaking representation Two-parameter Poisson-Dirichlet process.
2012/11/23
In this paper, we develop simple, yet efficient, procedures for sampling approximations of the two-Parameter Poisson-Dirichlet Process and the normalized inverse-Gaussian process. We compare the effic...
Estimating Player Contribution in Hockey with Regularized Logistic Regression
Logistic Regression Regularization Lasso Bayesian Shrinkage Sports Analytics
2012/11/23
We present a regularized logistic regression model for evaluating player contributions in hockey. The traditional metric for this purpose is the plus-minus statistic, which allocates a single unit of ...
On Control Charts for Monitoring the Variance of a Time Series
control charts CUSUM charts generalized likelihood ratio SPRT Shiryaev-Roberts procedures variance changes time series statistical process control sequential detection
2012/11/22
In this paper we derive control charts for the variance of a Gaussian process using the likelihood ratio approach, the generalized likelihood ratio approach, the sequential probability ratio method an...
Probabilistic Auto-Associative Models and Semi-Linear PCA
Probabilistic Auto-Associative Models Semi-Linear PCA
2012/11/22
Auto-Associative models cover a large class of methods used in data analysis. In this paper, we describe the generals properties of these models when the projection component is linear and we propose ...

Venezuelan Elections Vigilad las elecciones venezolanas
2012/11/22
Starting with the 2004 recall referendum, an important opposition sector to President Chavez has questioned the integrity of the Venezuelan electoral system, and casts doubt on the legitimacy and impa...
Evidence for Conservatism in LHC SUSY Searches
Uncertainty estimation High Energy Physics
2012/11/22
The standard for discovery in the high energy physics community for claiming discovery of new physics is a $5\sigma$ excess in the observed signal over the estimated background. While a $3\sigma$ exce...
