This paper introduces a statistical model for the arrival times of connection events in a computer network. Edges between nodes in a network can be interpreted and modelled as poin…
Choosing Between Methods of Combining p-values
Nicholas Heard, Patrick Rubin-Delanchy
Combining p-values from independent statistical tests is a popular approach to meta-analysis, particularly when the data underlying the tests are either no longer available or are…
Detecting periodic subsequences in cyber security data
Matthew Price-Williams, Nick Heard, Melissa Turcotte
Statistical approaches to cyber-security involve building realistic probability models of computer network data. In a data pre-processing phase, separating automated events from th…
Bayesian anomaly detection methods for social networks
Nicholas A. Heard, David J. Weston, Kiriaki Platanioti +1
Learning the network structure of a large graph is computationally demanding, and dynamically monitoring the network over time for any changes in structure threatens to be more cha…
