Regularization and Variable Selection Via the Elastic Net

Summary We propose the elastic net, a new regularization and variable selection method. Real world data and a simulation study show that the elastic net often outperforms the la...

PLS-SEM: Indeed a Silver Bullet

Structural equation modeling (SEM) has become a quasi-standard in marketing and management research when it comes to analyzing the cause-effect relations between latent construc...

Accurate normalization of real-time quantitative RT-PCR data by geometric averaging of multiple internal control genes

The normalization strategy presented here is a prerequisite for accurate RT-PCR expression profiling, which, among other things, opens up the possibility of studying the biologi...

A Decision-Theoretic Generalization of On-Line Learning and an Application to Boosting

A Theory of Social Comparison Processes

Hypothesis I: There exists, in the human organism, a drive to evaluate his opinions and his abilities. While opinions and abilities may, at first glance, seem to be quite differ...

Preferred Reporting Items for Systematic Reviews and Meta-Analyses: The PRISMA Statement

Increasing Returns and Long-Run Growth

This paper presents a fully specified model of long-run growth in which knowledge is assumed to be an input in production that has increasing marginal productivity. It is essent...

The Mini-International Neuropsychiatric Interview (M.I.N.I.): the development and validation of a structured diagnostic psychiatric interview for DSM-IV and ICD-10

The Elements of Statistical Learning: Data Mining, Inference, and Prediction

High resolution two-dimensional electrophoresis of proteins.

A technique has been developed for the separation of proteins by two-dimensional polyacrylamide gel electrophoresis. Due to its resolution and sensitivity, this technique is a p...

Optical Constants of the Noble Metals

The optical constants $n$ and $k$ were obtained for the noble metals (copper, silver, and gold) from reflection and transmission measurements on vacuum-evaporated thin films at ...
