Summary statistics for inhomogeneous marked point processes

ABSTRACT

We propose new summary statistics for intensity-reweighted moment stationary marked point processes with particular emphasis on discrete marks. The new statistics are based on the $$n$$n-point correlation functions and reduce to cross $$J$$J- and $$D$$D-functions when stationarity holds. We explore the relationships between the various functions and discuss their explicit forms under specific model assumptions. We derive ratio-unbiased minus sampling estimators for our statistics and illustrate their use on a data set of wildfires.
