Functional response additive model estimation with online virtual stock markets
Yingying Fan, Natasha Foutz, Gareth M. James +1
While functional regression models have received increasing attention recently, most existing approaches assume both a linear relationship and a scalar response variable. We sugges…
Improved variable selection with Forward-Lasso adaptive shrinkage
Peter Radchenko, Gareth M. James
Recently, considerable interest has focused on variable selection methods in regression situations where the number of predictors, , is large relative to the number of observati…
Sparse regulatory networks
Gareth M. James, Chiara Sabatti, Nengfeng Zhou +1
In many organisms the expression levels of each gene are controlled by the activation levels of known "Transcription Factors" (TF). A problem of considerable interest is that of es…
A multivariate adaptive stochastic search method for dimensionality reduction in classification
Tian Siva Tian, Gareth M. James, Rand R. Wilcox
High-dimensional classification has become an increasingly important problem. In this paper we propose a "Multivariate Adaptive Stochastic Search" (MASS) approach which first reduc…
Curve alignment by moments
Gareth M. James
A significant problem with most functional data analyses is that of misaligned curves. Without adjustment, even an analysis as simple as estimation of the mean will fail. One commo…
