I congratulate the authors for this excellent and timely work. Publications in microarray data analysis to date have concentrated on methodological issues, including the critical step of normalization as the authors have addressed in this article, among many others. There are few articles that deal with the theoretical aspect of the statistical approaches, making the present article a welcome and novel contribution to the field. Similar models to the authors' model (1),
[Y.sub.gi] = [[alpha].sub.g] + [[beta].sub.r.sub.gi] + [[gamma].sub.c.sub.gi] + m([X.sub.gi]) + [[epsilon].sub.gi],
have been proposed and used in the microarray data analysis. Here [[alpha].sub.g] is ...
