Ensembled Prediction Intervals for Causal Outcomes Under Hidden Confounding

no code implementations15 Jun 2023 Myrl G. Marmarelis, Greg Ver Steeg, Aram Galstyan, Fred Morstatter

We present a simple approach to partial identification using existing causal sensitivity models and show empirically that Caus-Modens gives tighter outcome intervals, as measured by the necessary interval size to achieve sufficient coverage.

A multivariate Hawkes process enables self- and cross-excitations through a triggering matrix that behaves like an asymmetrical covariance structure, characterizing pairwise interactions between the event types.
