Determining and Evaluating High-Risk Zones

Description

Functions for determining and evaluating high-risk zones and simulating and thinning point process data, as described in 'Determining high risk zones using point process methodology - Realization by building an R package' Seibold (2012) and 'Determining high-risk zones for unexploded World War II bombs by using point process methodology', Mahling et al. (2013) .
