Comparison of Methods for Imputing Social Network Data
- Computer ScienceJournal of Data Science
- 2022
Evaluating a more extensive set of eight network imputation techniques under more practical conditions shows that the effectiveness of imputation methods differs by missing data types, missing data mechanisms, the evaluation criteria used, and the complexity of the social networks.
Imputation of missing network data: Some simple procedures
- Computer ScienceJ. Soc. Struct.
- 2009
This paper investigates the use of some simple imputation procedures to handle missing network data, and the results of a simulation study show that ignoring the missing data can have large negative effects on structural properties of the network.
The Impact of Non-Response Treatments on the Stability of
- Computer Science
- 2011
The Adjusted Rand Index and the proportion of incorrect blocks in a blockmodel to describe the level of (dis)similarity are used and the amount and type of non-response, as well as the treatments of this form of missing data, all have an impact on the resulting blockmodel structures.

The main reasons for missingness in multiple-network systems are discussed, then the relation between various types of missing information and their effect on network properties are explored.
Stability of centrality measures in valued networks regarding different actor non-response treatments and macro-network structures
- Computer ScienceNetwork Science
- 2017
Simulations indicate that the amount of non-respondents, the type of underlying macro-structure, and the employed treatment have an impact on centrality scores, and regardless of the underlying network structure the median of the 3-nearest neighbors based on incoming ties performs the best.

NETWORK DATA AND MEASUREMENT
- Computer Science
- 1990
Continued research on data quality is needed; beyond improved samples and further investigation of the informant accuracy/reliability issue, this should cover common indices of network structure, address the consequences of sampling portions of a network, and examine the robustness of indicators ofnetwork structure and position to both random and nonrandom errors of measurement.
Mixing patterns in networks.
- Computer SciencePhysical review. E, Statistical, nonlinear, and soft matter physics
- 2003
This work proposes a number of measures of assortative mixing appropriate to the various mixing types, and applies them to a variety of real-world networks, showing that assortsative mixing is a pervasive phenomenon found in many networks.
Community structure in social and biological networks
- Computer ScienceProceedings of the National Academy of Sciences of the United States of America
- 2002
This article proposes a method for detecting communities, built around the idea of using centrality indices to find community boundaries, and tests it on computer-generated and real-world graphs whose community structure is already known and finds that the method detects this known structure with high sensitivity and reliability.

Network robustness and fragility: percolation on random graphs.
- MathematicsPhysical review letters

This paper studies percolation on graphs with completely general degree distribution, giving exact solutions for a variety of cases, including site percolators, bond percolations, and models in which occupation probabilities depend on vertex degree.
Random graphs with arbitrary degree distributions and their applications.
- MathematicsPhysical review. E, Statistical, nonlinear, and soft matter physics
- 2001
It is demonstrated that in some cases random graphs with appropriate distributions of vertex degree predict with surprising accuracy the behavior of the real world, while in others there is a measurable discrepancy between theory and reality, perhaps indicating the presence of additional social structure in the network that is not captured by the random graph.
