WebPrediction Analysis of Microarrays (PAM) is a statistical technique for class predic-tion using gene expression data using shrunken centroids. It is described in [3]. The method of nearest shrunken centroids identiﬁes subsets of genes that best character-ize each class. WebPolymer microarrays are a key enabling technology for the discovery of novel materials. This technology can be further enhanced by expanding the combinatorial space represented on an array. However, not all materials are compatible with the microarray format and materials must be screened to assess their suitability with the microarray manufacturing …
