From: An analysis of intra array repeats: the good, the bad and the non informative
Error rates after averaging pairs of probe sets. The transcription values reported by pairs of probe sets was averaged and compared to the values obtained by each probe set alone. The frequency of cases in which the average wrongly reports changes in transcription of at least two fold (blue) or wrongly reports constant transcription (red) is shown to five exclusive ranges of P values.
