Microarray Data Analysis Normalization Clustering Normalization use all genes in sample, OR use designated unchanging subset of genes measure variance of normalizing set use to generate expected variance, confidence intervals use Cls to define up-and down-regulated genesMicroarray Data Analysis - Normalization & Clustering • Normalization - use all genes in sample, OR - use designated unchanging subset of genes - measure variance of normalizing set - use to generate expected variance, confidence intervals - use CIs to define up- and down-regulated genes
