From: Unsupervised assessment of microarray data quality using a Gaussian mixture model
Quality Statistic1 | Description |
---|---|
pm.mean | mean of the raw intensity for all PM probes, prior to any normalizations. |
bgrd.mean | mean of the raw intensity for all probes used to compute background intensity. (Note: may be higher than pm.mean because GC compositions of probes used to compute background and PM probes can be quite different.) |
pos.vs.neg.auc | area under ROC curve discriminating between positive control probesets and negative control probesets. |
probeset.mean, probeset.stdev | mean and standard deviation of probeset signals after normalization. 2 |
probeset.mad.residual.mean, probeset.mad.residual.stdev | mean and standard deviation of the absolute deviations of the RMA probe level model residuals from the median across chips. 2 |
probeset.rle.mean, probeset.rle.stdev | mean and standard deviation of the absolute values of the relative log expression (RLE) for all probesets. 2 |
