Figure 2From: Normalization of two-channel microarrays accounting for experimental design and intensity-dependent relationshipsFunctions used in simulation. Functions used in simulated example for dye (left) and array (right) effects. The actual dye 'effect' functions (the δs in equation 2) are the dye-specific deviations from the average curve. The array functions sum to zero at any point on the x-axis.Back to article page
