Practical Quality Assessment of Microarray Data by Simulation of Differential Gene Expression [chapter]

Brian E. Howard, Beate Sick, Steffen Heber
2009 Lecture Notes in Computer Science  
We compare our method to expert annotations derived using popular quality diagnostics and show, with examples, that the decision to discard a chip depends on the details of the particular experiment.  ...  This technique simulates a set of differentially expressed genes and then assesses whether discarding each chip enhances or obscures the recovery of this known set.  ...  To test this hypothesis, we repeated the quality simulation with one modification: we used the "arrayWeights" functionality of the LIMMA package to identify and downweight noisy chips.  ...
