Title: Correcting for Unwanted Variation in Microarray Data 

Abstract: Principal components have been used a lot with microarray data to exhibit
unwanted variation, and to some extent to remove such variation.  Such efforts are also
called normalization.  In this talk I will review some of these methods, and related
work, and propose a simple but apparently novel variant which works a lot of the time,
though not always.  Part of my story will be a discussion of how one tells whether one
is helping or hurting the analysis by adjusting.  

Joint work with Johann Gagnon-Bartsch
