DOI: 10.1002/ece3.3298
Abstract: Abstract Local tree species diversity is maintained in part by conspecific negative density dependence (CNDD). This pervasive mechanism occurs in a variety of forms and ecosystems, but research to date has been heavily skewed toward… read more here.

DOI: 10.1007/s10898-018-0653-y
Abstract: The small-field astrometric point-pattern matching problem is a fundamental problem in astronomy, that although considered a long time ago still lacks a formal definition. It can be textually stated as: given two lists of positions… read more here.

DOI: 10.1007/s11222-020-09932-y
Abstract: We introduce the transport–transform and the relative transport–transform metrics between finite point patterns on a general space, which provide a unified framework for earlier point pattern metrics, in particular the generalized spike time and the… read more here.

DOI: 10.1016/j.gecco.2017.11.001
Abstract: Abstract Spatial point-pattern analysis can give insights to the underlying processes of patch succession and restoration. It is unclear whether inter-shrub competition determines patch succession. In this paper, we assessed the spatial patterns along patch… read more here.

Identifying a spatial scale for the analysis of residential burglary: An empirical framework based on point pattern analysis

DOI: 10.1371/journal.pone.0264718
Abstract: A key issue in the spatial and temporal analysis of residential burglary is the choice of scale: spatial patterns might differ appreciably for different time periods and vary across geographic units of analysis. Based on… read more here.

DOI: 10.5705/ss.202015.0426
Abstract: The two-point correlation function (2PCF) is a measure of the secondorder properties of a spatial point pattern and is commonly used in astronomy. We introduce an asymptotic mean squared error (AMSE) approach to obtain closedform… read more here.
