Meaning of BIN in English
Those pairs of points that have similar distance and direction are put into the same bin. The squared difference of their values are then averaged and multiplied by 0.5 to give one empirical semivariogram value per bin.
Note: Bins are shown as cells in the semivariogram surface.
