Symbol	Description
$A_i$	The ith point of category A.
$P_{A_i\to BC}^{\prime }$	The probability of the actual simultaneous occurrence of points of category B and points of category C in the neighbourhood of ith point of category A.
PA→BC	The expected probability of simultaneous occurrence of points of category B and points of category C in the neighbourhood of points of category A.
$N_{A_i\to BC}$	The probability of simultaneous occurrence of points of category B and points of category C in the neighbourhood of the ith point of category A.
NB	The number of points of category B in the study area.
N	The total number of points of all categories in the study area.
$N_{A_{i}B}^{\prime }$	The number of points of category B in the neighbourhood of the ith point of category A.
$N_{A_i}^{\prime }$	The total number of points of all categories in the neighbourhood of the ith point of category A.
Wij	The geographical weight of the jth adjacency point in the neighbourhood of the ith point of category A.
dij	The distance from the ith point of category A to the jth adjacency point.
bi	The bandwidth Euclidean distance of the ith point of category A.
f(j,X)	Represents a binary function. The value of f(j,X) is 1 when the category of the jth adjacent point of the ith point of category A is X, and the value of f(j,X) is 0 when the category of the jth adjacent point of the ith point of category A isn't X. X represents the category of a point.
$P_{A\to B...Z}^{\prime }$	The probability of simultaneous occurrence of points of category B...Z in the neighbourhood of the ith point of category A.
PA→B...Z	The probability of simultaneous occurrence of B...Z points in the global scope.
NB	The number of points of category B in the global scope.
Nn	The number of points of category n in the global scope.
N	The total number of points of all categories in the global scope.
s	The number of starting point set.
m	The number of simulation times.
K	The number of the nearest neighbours.
