Window of cells with similar concentrations. The cell which represents x[t, e] is shown in red, and a purple line points towards this cell. The window of cells with similar factor concentrations is shown in gray, and cells farther away from the red-colored cell are less similar. Cells with more similar concentrations are shown by darker shades of gray, and cells not in the window are colored white. The black lines show the boundaries of the experimental eve pattern. The NODE method takes the amount of similarity of the cells into account when doing the regression procedure.
