“…In HP, the points are distributed in accordance with an intensity function λ( x , y ) that varies with location ( x , y ) (Wiegand & Moloney, ; Zhu, Getzin, Wiegand, Ren, & Ma, ; Hypotheses 1, Table ). g ( r ) is related to the derivative of the K function (Equation ): A is the area of the study region, n is the number of the points of species, d ij is the distance between focus point i and the other point j , I r is a counter variable ( I r ( d ij ) = 1 if d ij < r , and I r ( d ij ) = 0 otherwise), and w ij is a weighting factor to correct for the edge effects (Silva et al., ; Wiegand & Moloney, ).…”
