Figure 1From: The partitioned LASSO-patternsearch algorithm with application to gene expression dataDiagram of the subproblems in the first stage of pLPS, assuming 5 partitions. Side length of a square is the partition size, while the horizontal axis contains the labels of the first effect and the vertical axis the label of the second effect. Squares filled with red dots are “type-one” subproblems while the triangles filled with green dots are “type-two” subproblems.Back to article page
