Estimating second-order characteristics of inhomogeneous spatio-temporal point processes

Non-parametric estimates of the K-function and the pair correlation function play a fundamental role for exploratory and explanatory analysis of spatial and spatio-temporal point patterns. These estimates usually require information from outside of the study region, resulting to the so-called edge effects which have to be corrected. They also depend on first-order characteristics, which have to be estimated in practice. I extended classical edge correction methods to the spatio-temporal setting and compared the performance of the related estimators for stationary/non-stationary and/or isotropic/anisotropic point patterns. Further, I explored the influence of the estimated intensity function on these estimators.

Project on Robust and Optimal Locations for Sustainable Environment and Systems

The aim of this interdisciplinary project is to provide to decision makers and planners of the geographic space reliable and relevant information allowing them to evaluate characteristics and properties of several centres in theoretical or practical geographic context, thus according to different spatial patterns of demand points.
