2016/1/20
Influence diagnosis is important since presence of influential ob-servations could lead to distorted analysis and misleading interpreta-tions. For high dimensional data, it is particularly so, as the ...

2012/9/18
The fundamental building block of social in uence is for one person to elicit a response in another. Researchers measur-ing a \response" in social media typically depend either on detailed models of h...
Clustering function: a measure of social influence
clustering coecient power law social network intersection graph
2012/9/19
A commonly used characteristic of statistical dependence of adjacency relations in real networks, the clustering coecient, evaluates chances that two neighbours of a given vertex are adjacent. Anothe...
Co-evolution of Selection and Influence in Social Networks
Co-evolution Selection Influence Social Networks
2011/7/7
Many networks are complex dynamical systems, where both attributes of nodes and topology of the network (link structure) can change with time. We propose a model of co-evolving networks where both nod...

2009/9/25
Allen and Ng (1999a) proposed a conceptual framework of how consumers’ choice of services may be influenced by the human values that they endorse. The aim of this study is to observe which implicatio...

Vertices of degree one a random sphere of influence graph
2009/9/22
The sphere of influence graph of the set of vertices in R~
is constructed by identifying the nearest neighbour of each vertex,
centering a ball at each vertex so that its nearest neighbour lies on t...

ASSESSMENT OF INFLUENCE OF INDIVIDUAL OBSERVATIONS ON PREDICTION MEAN SQUARE ERRORS IN VARIABLE SELECTION PROBLEMS
Cook's distance influence measure influential observation Mallows'CP statistic regression diagnostics sensitivity analysis
2009/3/10
A new influence measure is proposed to assess the influence of individual observations on prediction mean square errors (PMSE) in variable selection problems. It is based on the estimated PMSE which c...
