Statistical inference for network samples using subgraph counts

1 code implementation2 Jan 2017 P-A. G. Maugis, Carey E. Priebe, S. C. Olhede, P. J. Wolfe

Our results yield joint confidence regions for subgraph counts, and therefore methods for testing whether the observations in a network sample are drawn from: a specified distribution, a specified model, or from the same model as another network sample.

Fast counting of medium-sized rooted subgraphs

1 code implementation31 Dec 2016 P-A. G. Maugis, S. C. Olhede, P. J. Wolfe

We prove that counting copies of any graph $F$ in another graph $G$ can be achieved using basic matrix operations on the adjacency matrix of $G$.

Higher-Order Properties of Analytic Wavelets

1 code implementation17 Feb 2008 J. M. Lilly, S. C. Olhede

Wavelet behavior is found to be strongly impacted by the degree of asymmetry of the wavelet in both the frequency and the time domain, as quantified by the third central moments.
