Simulation 2: assessing the effects of increasing the number of subjects on the learned group networks. (a) The group-level network, with 20 nodes and an average of two connections per node. (b) The FDR curves (with standard deviation marked) of the proposed gPC_fdr algorithm, the original PC_fdr algorithm by pooling all subject data together, and the IMaGES algorithm. (c) The type I error rate curves. (d) The detection power curves. The x-axis represents the number of subjects within the group.
