DWD platform parameter transfer. One treatment group was used as a training set for DWD to transform another treatment group in the MAQC and human sperm data sets. Titles indicate treatment groups used. Scrambled: Same as transfer, but parameters were randomly re-ordered before being used for cross-platform normalization. Self.transfer: Full human sperm data set was used for training. Transfer: Indicated treatment group was used as a training set. No.transfer: No additional training set was used. Boxes show the interquartile range and whiskers extend to an additional 1.5 times the interquartile range. Values outside the whiskers are plotted as circles. Notches are drawn such that non-overlapping notches are strong evidence of differing medians [61, 45].
