Signal precision. Signal precision for different spike-in concentration ranges. For each 2-fold spike-in concentration step the fold change and average expression of every spike-in probe set was determined over the arrays where the concentration step takes place. The fold change was compared to the fold change of 1000 probes closest in average expression (on the same arrays). The ranks are combined for a low, middle, and high spike-in concentration range, and an averaged AUC score is calculated.
