Figure 3From: Model-based analysis of oligonucleotide arrays: model validation, design issues and standard error applicationHistogram of correlations between model-based expression values estimated using the 20-probe difference model and those estimated using different models. (a) 10-probe difference model; (b) 20-probe PM-only model; (c) 20-probe MM-only model. All comparisons are across the 21 arrays in array set 1.Back to article page
