Lab accounts for more variability in quality than tissue type. Resulting from fitting Model 2. The individual random effects for lab and tissue are plotted and the estimated variance for each effect is reported. These estimates suggest that the lab in which an array was hybridized accounts for more of the variability in microarray data quality than the tissue that was hybridized to the array.
