Relational exchangeability
Harry Crane, Walter Dempsey
A relationally exchangeable structure is a random combinatorial structure whose law is invariant with respect to relabeling its relations, as opposed to its elements. Aside from ex…
Edge exchangeable models for network data
Harry Crane, Walter Dempsey
Exchangeable models for countable vertex-labeled graphs cannot replicate the large sample behaviors of sparsity and power law degree distribution observed in many network datasets.…
A framework for statistical network modeling
Harry Crane, Walter Dempsey
Basic principles of statistical inference are commonly violated in network data analysis. Under the current approach, it is often impossible to identify a model that accommodates k…
The pilgrim process
Walter Dempsey, Peter McCullagh
Pilgrim's monopoly is a probabilistic process giving rise to a non-negative sequence that is infinitely exchangeable, a natural model for time-to-event data. The…
Weak continuity of predictive distribution for Markov survival processes
Walter Dempsey, Peter McCullagh
We explore the concept of a consistent exchangeable survival process - a joint distribution of survival times in which the risk set evolves as a continuous-time Markov process with…
