Geometrically Corrected Second Order Analysis of Events on a Linear Network, with Applications to Ecology and Criminology (2012, methodology): “Examples include traffic accidents and vehicle thefts on a road network (Yamada & Thill, 2004; Lu & Chen, 2007; Xie & Yan, 2008); roadside trees or invasive species in an agricultural area (Spooner et al., 2004; Deckers et al., 2005) and green spaces, retail stores or roadside kiosks accessible…”
Kernel Density Estimation on a Linear Network (2017, background): “The ‘points’ may be traffic accidents, vehicle thefts or street crimes (Yamada & Thill, 2004; Lu & Chen, 2007; Xie & Yan, 2008; Ang et al., 2012); roadside trees or invasive species (Spooner et al., 2004; Deckers et al., 2005); retail stores, roadside kiosks or urban parks (Okabe & Kitamura, 1996;…”
Spatial data mining and geographic knowledge discovery - An introduction (2009, background): “Increasingly statistics for the detection of spatial clusters are available for non-Euclidean spaces, particularly network spaces (Shiode & Shiode, 2009; Xie & Yan, 2008; Yamada & Thill, 2007).”
A kernel density estimation method for networks, its computational method and a GIS‐based tool (2009, methodology): “Xie and Yan ( 2008 ) developed a kernel density estimation method on a network, but they did not discuss the bias of their estimator explicitly.”
