Nonisomorphic Graphs Can Share an Arbitrarily Large Fraction of Their Vertex-Deleted Cards

Sergey Ivanov

For a graph , its vertex deck is the multiset of graphs obtained by deleting one vertex. Bowler, Brown, and Fenner (BBF) proposed as the maximum possibl…

Universal Inference for model selection on networks

Eric Yanchenko, Jonathan P. Williams, Ryan Martin

Model selection and hypothesis testing are important tasks on networks. A key challenge lies in the inherent dependence in network data, as well as the fact that typically only a s…

Decision-making with possibilistic inferential models

Ryan Martin, Shih-Ni Prim, Jonathan Williams

Inferential models (IMs) are data-dependent, imprecise-probabilistic structures designed to quantify uncertainty about unknowns. As the name suggests, the focus has been on uncerta…

Hypothesis testing for community structure in temporal networks using e-values

Eric Yanchenko, Jonathan P. Williams, Ryan Martin

Community structure in networks naturally arises in various applications. But while the topic has received significant attention for static networks, the literature on community st…

Generalized Universal Inference on Risk Minimizers

Neil Dey, Ryan Martin, Jonathan P. Williams

A common goal in statistics and machine learning is estimation of unknowns. Point estimates alone are of little value without an accompanying measure of uncertainty, but traditiona…

Asymptotic efficiency of inferential models and a possibilistic Bernstein--von Mises theorem

Ryan Martin, Jonathan P. Williams

The inferential model (IM) framework offers an alternative to the classical probabilistic (e.g., Bayesian and fiducial) uncertainty quantification in statistical inference. A key d…
