Evaluation of preprocessing methods in reducing technical variance using PBLs dataset. a Density distribution of Beta values in six replicates in the raw data. b Density distribution of Beta values in six replicates in the data processed by Noob + BMIQ. c Loess curve fitted to the scatterplot of standard deviation versus average of methylation Beta values for different processing methods. d Boxplot of absolute difference in methylation Beta values between adjacent type1-type2 probe pairs in PBLs dataset, averaged across six replicates
