626 Spatial Point Patterns: Methodology and Applications with R
At the time of writing, spatstat provides c ode for simulating such processes, but not yet
for fitting these models to point pattern data. We expect this to ch ange soon. The lgcp package
[650, 651] ca n fit multitype log-Gaussian Cox process models to multitype p oint pattern data.
14.10.1 Multitype Cox processes
A multitype Cox process is effectively a multitype Poisson process w hose driving intensity is a
random function Λ(u,m). If there are M possible mar ks, a multitype Cox process is equivalent to
