17.4.4 Intensity for multitype point patterns
The datasets chicago and dendrite are examples of multitype point patterns on linear networks,
where points are classified into different types.
We use the notatio n for multitype point patterns an d point processes that was estab lished in
Chapter 14. On a linear network L, a multitype po int pattern dataset y, with each point belonging
to one of M possible categories or types, is a finite set y = {(x
1
,m
1
),... ,(x
n
,m
n
)} whe re x
k
∈ L
is the location of the kth point and m
k
∈ {1,2,..., M} is the type classification of the kth point,
k = 1, 2,. ..,n, and the number n of random points is not fixed in advance.
