Clark Evans

Clark Evans is a statistician known for developing the Clark Evans index, a measure used in spatial analysis to determine whether points (like trees or city locations) are randomly distributed, clustered, or evenly spaced in an area. It compares the average distance between each point and its nearest neighbor to what would be expected if points were randomly placed. Values close to 1 suggest randomness; less than 1 indicates clustering; greater than 1 implies uniform spacing. This helps researchers understand the spatial patterns and relationships within geographic data.
