Modeling Over-Dispersion for Network Data Clustering

2017 16th IEEE International Conference on Machine Learning and Applications (ICMLA), 2017
Over-dispersed network data mining has emerged as a central theme in data science, evident by a sharp increase in the volume of real-world network data with imbalanced clusters.While most of existing clustering methods are designed for discovering the number of clusters and class specific connectivity patterns, few methods are available to uncover the ...

The over-dispersion between cells of chromosomal aberrations

Journal of Theoretical Biology, 1979
Abstract A survey of the literature suggests that random dispersion of radiation induced aberrations occurs only when uniform fields of predominantly low LET radiations act on cell populations which are homogeneous with regard to cell type, cycle stage and intrinsic radiosensitivity.

Confidence Interval of a Proportion with Over-dispersion

Biometrical Journal, 2002
A new approach that extends the classical Clopper-Pearson procedure is proposed for the estimation of the (1–α)% confidence interval of a proportion with over-dispersion. Over-dispersion occurs when a proportion of interest shows more variation (variance inflation) than predicted by the binomial distribution. There are two steps in the approach. The

Over-Dispersion, Credibility Adjustments, Mixed Models, and Regularization

Springer Actuarial, 2019
Data sets exhibiting a hierarchical or nested structure, or including longitudinal or spatial elements often arise in insurance studies. This generally results in correlation among the responses within the same group, casting doubts about the outputs of analyses assuming mutual independence.

Predation: an overrated factor for over-dispersion of birds' nests?

Animal Behaviour, 1991
It is generally assumed that cryptic prey, such as birds' nests, should be over-dispersed as a defence against predation. This suggestion is based on the idea that predators intensify their searching effort in an area around prey items they have found and on frequent observations of predation rate going up with increasing prey density.
