Fig. 1From: Leveraging pleiotropic association using sparse group variable selection in genomics dataEach row in the figure corresponds to a simulated scenario. Colours correspond to groups, and the number active in a group refers to the number of non-zero variables pa in a group consisting of 20 variables per study (so 40 variables over K=2 studies). The number of non-zero vs zero groups is (1/4,2/8,4/16 and 8/32)Back to article page
