High-order accurate inference on manifolds

This work develops a bootstrap algorithm on Riemannian manifolds that is both computationally efficient and accurate for hypothesis testing and confidence region construction, and establishes high-order asymptotics under an appropriate coordinate representation induced by a second-order retraction.

From Good Starts to Optimal Inference: Generalized Latent Factor Models with Missingness and Implicit Regularization

A theory is developed that connects a computationally tractable nonconvex procedure directly to statistical inference for nonlinear latent factor models with exponential-family links and partially observed entries with severe missingness, weak low-rank signals, and diminishing local curvature.
