| | NCIi is calculated as follows (simplifying the notation):
NCIi = Σ λk((DBHk)α/distanceβ)
where:
- we're summing over k = 0 to N neighbors greater than the minimum
neighbor DBH
- α is the neighbor DBH effect parameter
- β is the neighbor distance effect parameter
- DBH is of the target tree, in cm
- DBHk is the DBH of the kth neighbor, in meters
- γ is the size sensitivity to NCI parameter
- λk is the NCI lambda parameter for the species
of the kth neighbor
- distance is distance from target to neighbor, in meters
