Lag distance, even without a specified unit, measures the spatial separation between sample points. It represents the relative distances between points rather than an absolute measurement. For instance, if you have sample points from a grid, the lag distance could be the number of grid cells between points. It quantifies how far apart the points are, allowing the variogram to model spatial relationships based on these separations. The actual units depend on the context of the data (e.g., meters, kilometers, etc.), but the concept remains the same regardless of unit.
Amazing!!!
Thanks for sharing...
Very interesting! What is lag distance measuring if there isn't a distance unit?
