Bayesian method corrects timing misalignment in recurrent event studies.
problem Estimating differences in event rates under two treatments with timing misalignment.
method g-computation procedure with joint semiparametric Bayesian model.
result Correctly estimates average causal effects under right-censoring.
A Riemannian metric on a manifold M induces a family of Riemannian metrics on the loop space LM depending on a Sobolev space parameter s. We compute the connection forms of these metrics and the higher symbols of their curvature forms, which take values in pseudodifferential operators. These calculations are used in a …
This paper provides an explicit rate bound for over-relaxed ADMM.
problem Computing upper bounds on the convergence rate of ADMM.
method Reduces the problem to SDP and solves it analytically.
result Provides a general and explicit upper bound on the convergence rate of ADMM.
We generalize the familiar notions of overtwistedness and Giroux torsion in 3-dimensional contact manifolds, defining an infinite hierarchy of local filling obstructions called planar torsion, whose integer-valued order can be interpreted as measuring a gradation in "degrees of tightness" of contact manifolds…
