We restrict our attention to space-time point pattern data for which we havea single realisation within a finite region. Second-order characteristics areused to analyse the spatio-temporal structure of the underlying point process.In particular, the space-time inhomogeneous pair correlation function and$K$-function measure the spatio-temporal clustering/regularity and thespatio-temporal interaction, and thus help with model choice. Non-parametricestimators of the second-order characteristics require information from outsidethe study region, resulting to the so-called edge effects which have to becorrected, and depend on first-order characteristics, which have to beestimated in practice. Here, we extend classical edge correction factors to thespatio-temporal setting and compare the performance of the related estimatorsfor stationary/non-stationary and/or isotropic/anisotropic point patterns.Then, we explore the influence of estimated intensity function on theseestimators.
