Abstract:
|
Microarray experiments represent a substantial investment of time and resources. The power of a microarray study is greatly affected by the experimental design employed. We will review the principles of experimental design as they pertain to microarray studies, and then discuss results from an experiment where the same RNA samples were studied using two different experimental plans. The theoretical relative efficiency of the two designs will be compared with the actual results. In addition, we introduce refinements of ANOVA modeling of microarray data and inferential tools for gene expression data.
