404 Spatial Point Patterns: Methodology and Applications with R
The MAD test and DCLF test require us to choose the range of distance values over which
the deviations in the summary function will be maximised or summed. It can be quite useful to
plot a significance trace for these tests against the length of the range of distances. The f unctions
mad.sigtrace, dclf.sigtrace, and mctest.sigtrace generate significance traces for the cor-
respond ing tests. Fig ure 10.9 shows the result of
> dclf.sigtrace(cells, Lest, nsim=19)
The black line is the Monte Carlo p-value based on 19 simulations for the DCLF test over th e
distance range [0,R ] plotted against ...
