  d = diameter at breast height (DBH, 1.3 m) [cm]   S = local stand density index within 2.5 × crown radius
D = mean distance of nearest neighbours [m]  d= quadratic mean stem diameter of nearest neighbours [cm]
 Nearest neighbour range is within a radius of 10 m around the central tree. p= growth quantile
    α = weight
