Fine asymptotics for approximate simulation of symmetric channels

Valentinian Lungu, Aaron B. Wagner, Ioannis Kontoyiannis

We study the approximate channel simulation problem in the normal approximation regime. Our starting point is the fact established by Cao et al.~\cite{Cao_channel_simulation}, that…

The relative value of interventional and observational samples in Bayesian Causal Linear Gaussian Models

Valentinian Lungu, Anish Dhir, Mark van der Wilk +1

We investigate the asymptotic properties of Bayesian bivariate causal discovery for Gaussian Linear Structural Equation Models (SEMs) with heteroscedastic noise. We demonstrate tha…
