The Framework of Relative Density-Based Clustering

open access: yes, 2017
Density-based clustering, using two-phase scheme which consists of an online component and an offline component, is an effective framework for data stream clustering, it can find arbitrarily shaped clusters and capture the evolving characteristic of real-

On Relative Ordered Turán Density [PDF]

open access: yes
For an ordered graph F, denote the Turán density by π→(F). The relative Turán density, denoted by ϱ(F), is the supremum over α ∈ [0, 1] such that every ordered graph G contains an F-free subgraph G′ with e(G′) ≥ αe(G).

Relative Distribution Methods in Stata [PDF]

open access: yes, 2008
The concept of the relative density seems like a fruitful nonparametric approach to studying distributional differences between groups (Handcock and Morris 1999), yet it appears that the technique has gone more or less unnoticed in applied social science
