Antimodes and Graphical Anomaly Exploration via Adaptive Depth Quantile Functions
Gabriel Chandler, Wolfgang Polonik
This work proposes and investigates a novel method for anomaly detection and shows it to be competitive in a variety of Euclidean and non-Euclidean situations. It is based on an ex…
Testing For Global Covariate Effects in Dynamic Interaction Event Networks
Alexander Kreiss, Enno Mammen, Wolfgang Polonik
In statistical network analysis it is common to observe so called interaction data. Such data is characterized by actors forming the vertices and interacting along edges of the net…
High Order Adjusted Block-wise Empirical Likelihood For Weakly Dependent Data
Guangxing Wang, Wolfgang Polonik
It is well known that the empirical likelihood ratio confidence region suffers finite sample under-coverage issue, and this severely hampers its application in statistical inferenc…
Local Neighborhood Fusion in Locally Constant Gaussian Graphical Models
Apratim Ganguly, Wolfgang Polonik
In this paper we penetrate and extend the notion of local constancy in graphical models that has been introduced by Honorio et al. (2009). We propose Neighborhood-Fused Lasso, a me…
