Similarity to absent or find sites (SumSim)

Source data

Input exemplar cases must be in three columns: 1 or 0 in the first column meaning find site or absence site, Lambert-Est X coordinate in the second and Y coordinate in the third column. Set direction of the axes from the radio button above the input cell. Lines beginning with a character are removed. Every case must be in a separate row, column separator can be either space, tab or semicolon, decimal separator can be either point or comma. The SumSim algorithm is used in the software system Constud. See chapter 4.1.1 in the Constud Tutorial and an explanatory figure.
