Consistent selection of tuning parameters via variable selection stability
kappa coefficient penalized regression selection consistency stability tuning
2012/9/17
Penalized regression models are popularly used in high-dimensional data analysis to conduct variable selection and model fitting simultaneously. Whereas success has been widely reported in literature,...

The areal modeling of the extremes of a natural process such as rainfall or temperature is important in environmental statistics; for example, understanding extreme areal rainfall is crucial in flood ...
Correction on Moments of minors of Wishart matrices
Compound matrix graphical models multivariate analysis random determinant random matrix tetrad.
2012/9/17
Theorem 5.7 in [1] gives a formula for the variance of a minor (i.e., a sub-determinant) of a Wishart random matrix. The formula has to be corrected as follows.
Test for bandedness of high-dimensional covariance matrices and bandwidth estimation
Banded covariance matrix bandwidth estimation high data dimension largep, small n nonparametric.
2012/9/17
Motivated by the latest effort to employ banded matrices to esti-mate a high-dimensional covariance Σ, we propose a test for Σbeing banded with possible diverging bandwidth. The test is adaptive to th...

2012/9/17
Closure-based multiple testing procedures for con-trolling the familywise error rate (FWER) have been around for decades, but they have not been well un-derstood, and hence have been under-appreciated...

2012/9/17
Goeman and Solari [Statist. Sci.26 (2011) 584–597] have addressed the interesting topic of multiple testing for exploratory re-search, and provided us with nice suggestions for exploratory analysis.Th...
Asymptotic Generalization Bound of Fisher's Linear Discriminant Analysis
Asymptotic Generalization Bound Fisher's Linear Discriminant Analysis
2012/9/17
Fisher’s linear discriminant analysis (FLDA) is an important dimension reduction method in sta-tistical pattern recognition. It has been shown that FLDA is asymptotically Bayes optimal under the homos...

The Multivariate $S_n$ Estimator
Outlier detection robust estimation multivariate ranking multivariate statistics.
2012/9/17
In this note we introduce the MSn estimator (for Multivariate Sn) a new robust estimator of multivariate ranking. Like MVE and MCD it searches for anh-subset which mini-mizes a criterion. The differen...
Do cycles dissipate when subjects must choose simultaneously?

2012/9/18
This question is raised by Cason, Friedman and Hopkins (CFH, 2012) af-ter they firstly found and indexed quantitatively the cycles in a continuous time experiment. To answer this question, we use the ...
Metric distances derived from cosine similarity and Pearson and Spearman correlations
Metric distances derived cosine similarity Pearson and Spearman correlations
2012/9/17
We investigate two classes of transformations of cosine similarity and Pearson and Spearman correlations into metric distances, utilising the simple tool of metric-preserving functions. The rst class...
