Accuracy of MEA methods using constrained partition-maximization. The ability of different MEA methods to correctly rank the known TF motif in 237 yeast ChIP-chip experiments is shown. Each panel shows the accuracy of the Y constrained partition maximization (YCPM) of a method, along with the fixed partition (YFP) variant's accuracy for comparison. Each point shows the mean or median PRA (Y-axis) of the MEA method. For YCPM methods, the X-axis of the plot is the maximum value, b, that t y may assume; for YFP methods, it is the method's fixed threshold, t y .
