Analysing highly complex and highly structured point patterns in space
Eckardt, Matthias; Mateu, Jorge Elsevier (2017)The purpose of this paper is to discuss two recently introduced approaches that focus on structures of different events that occur randomly in space: spatial dependence graph models (SDGMs), and network intensity functions. ... -
Analysing Multivariate Spatial Point Processes with Continuous Marks: A Graphical Modelling Approach
Eckardt, Matthias; Mateu, Jorge Wiley (2019-04)This paper discusses the application of graphical modelling in the statistical analysis of marked point patterns. We consider a multivariate planar point process with quantitative marks. After a survey of statistical methods ... -
Graphical modelling and partial characteristics for multitype and multivariate-marked spatio-temporal point processes
Eckardt, Matthias; González, Jonatan A.; Mateu, Jorge Elsevier (2021-04)A method for dealing with multivariate analysis of marked spatio-temporal point processes is presented by introducing different partial point characteristics, and by extending the spatial dependence graph model formalism. ... -
Partial and semi-partial statistics of spatial associations for multivariate areal data
Eckardt, Matthias; Mateu, Jorge Wiley (2020-06-12)The analysis of correlation structures among multivariate spatially aggregated data has become increasingly important and poses substantial challenges. This article concerns the development of partial and semi‐partial ... -
Partial characteristics for marked spatial point processes
Eckardt, Matthias; Mateu, Jorge Wiley (2019-09)This paper introduces a new class of partial summary characteristics for twotypes of marked planar point processes. We consider purely qualitatively marked spatial point processes and multitype spatial point processes with ... -
Point Patterns Occurring on Complex Structures in Space and Space-Time: An Alternative Network Approach
Eckardt, Matthias; Mateu, Jorge Taylor & Francis (2017-10)This article presents an alternative approach of analyzing possibly multitype point patterns in space and space–time that occur on network structures, and it introduces several different graph-related intensity measures. ... -
Second-order and local characteristics of network intensity functions
Eckardt, Matthias; Mateu, Jorge Springer (2021)The last decade has witnessed an increase of interest in the spatial analysis of structuredpoint patterns over networks whose analysis is challenging because of geometricalcomplexities and unique methodological problems. ...
