Spatial dependency between a linear network and a point pattern
… properties of point processes in the form of Ripley's K-function for unmarked point patterns and the cross-K function for marked point patterns. We then get to the main focus of this mini-dissertation, that is, the spatial relationship between points and linear structures, particularly linear …

Spatial Pattern Analysis of Tree Species Distribution in a Central Appalachian Upland Heath Barren
… and spatial pattern. The spatial statistics, Ripley's K-function and nearest neighbor analysis, presented a series of different interaction types reflected across size-growth classes and species where the null hypothesis was rejected for some pairs and supported in others. The selected …

Spatial Patterns and Correlates of Lower Respiratory Tract Illnesses in Children from Drakenstein, Western Cape
… and cluster analysis was performed using Ripley's K function and Kullddorf spatial scan statistics. Finally, generalized additive models were used to identify socio-demographic factors associated with pneumonia and wheeze. Results: A total of 947 children were included in analysis, with …

Modeling spatial patterns of mixed-species Appalachian forests with Gibbs point processes
Stochastic point processes and associated methodology provide a means for the statistical analysis and modeling of the spatial point pattern formed from forest tree stem locations. Stochastic Gibbs point processes were explored as models that could simulate short-range clustering arising from …
