Mixture Model Parameter Estimates. Supervised (MLE) and Unsupervised (EM) estimates shown are for the following features from the 3' expression arrays: (A) 5th percentile of raw intensities, (B) inter-quartile range of the Relative Log Intensity (RLE), (C) 25th percentile of the probe-level model residuals, and (D) the 20th percentile of the probe-level model weights. All features were normalized relative to other chips in the same experiment, using the SCORE function (see Table 1).
