The study of the network between transcription factors and their targets is important for understanding the complex regulatory mechanisms in a cell. However, due to post-translational modifications the regulator transcription levels (as measured, e.g., by microarray expression arrays) generally...

We propose a novel method to model nonlinear regression problems by adapting the principle of penalization to Partial Least Squares (PLS). Starting with a generalized additive model, we expand the additive component of each variable in terms of a generous amount of B-Splines basis functions. In...

Partial Least Squares (PLS) is a highly efficient statistical regression technique that is well suited for the analysis of high-dimensional genomic data. In this paper we review the theory and applications of PLS both under methodological and biological points of view. Focusing on microarray...
