Upset graphs to show the intersections of features used to construct feasible regression models at four monitoring areas. (A) Upset graph for the monitoring area under the main deck; (B) Upset graph for the monitoring area at ship bottom (midship); (C) Upset graph for the monitoring area at ship bottom (port); (D) Upset graph for the monitoring area at ship bottom (starboard). The number for the black bar represents the number of features used to construct one feasible model. The number for the red bar denotes the number of features exactly used to construct some feasible regression models that are indicated by the dots and line below the bar.
