(a) Collection of s pieces exceeding a chosen threshold d (here s = 12 and d = 0.2; see Text ). The green line is the “true” functional representation of X₂ versus v₃. (b) Pairs in (a) are merged based on their distances and on the distances between two points in a pair. (c) The subgroups of pairs in (b) are merged. (d) The sigmoidal shape of points in (c) suggests that the flux of the smallest X₂ (~0.25) should be close to zero. The sum of errors between the estimated points and their corresponding true values (on the green line) is 0.0551.
