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
DBH_k is the DBH of the kth neighbor, in meters
γ is the size sensitivity to NCI parameter
λ_k is the NCI lambda parameter for the species of the kth neighbor
distance is distance from target to neighbor, in meters

Size effect is calculated as follows:

SE = 1 - exp (-d * DBH)
