Common statistical analysis methods such as ANOVA, factor analysis, and functional modeling with partially ordered basis sets also exhibit natural variable groupings. We develop a new variable selection method that respects the group constraint. Our new method enjoys benefits that existing successful methods do not have, while offering the potential for achieving theoretical ``oracle'' properties. \end{document}
