NSAF and GeneChip datasets have similar PLGEM parameters. NSAF and GeneChip datasets have similar PLGEM parameters. PLGEM was fitted on 101 publicly available GeneChip datasets, four relevant fitting parameters were recorded, and density distributions were plotted for each of these parameters. A, Pearson's correlation coefficients were calculated between all available ln(rowS.D.) values and the corresponding ln(rowMean) values. B, adjusted r2 values were calculated between the fitted PLGEM and the modeling points. Also shown are slopes (C) and intercepts (D) of the fitted model. Superimposed on the density plots are the actual values of the same four parameters as obtained from the mouse GeneChip (blue circles), the yeast NSAF (red squares), and the Mediator NSAF datasets (green diamonds).
