Weboccurs in globalnormalization, Lowess normalization,scaling, quantile, and VSN. Global normalization shifts the center of M-values of data to 0, and thus the observed changes on all levels of A-values are expected. Similarly, the scaling method enforces equal median absolute deviations in both M- and A-values. WebScaling approaches to normalization include global scaling, Lowess, and the Trimmed Mean Method (TMM) (Robinson and Oshlack, 2010). These approaches each use a different method to calculate a linear scaling factor. Global scaling uses a factor that is based on the difference in the means of the data sets to be compared.
