A note on breaking ties among sample medians
Peter M. Aronow, Donald K. K. Lee
Given samples , it is well known that any sample median value (not necessarily unique) minimizes the absolute loss . Interestingly, we show th…
Boosted nonparametric hazards with time-dependent covariates
Donald K. K. Lee, Ningyuan Chen, Hemant Ishwaran
Given functional data from a survival process with time-dependent covariates, we derive a smooth convex representation for its nonparametric log-likelihood functional and obtain it…
Super-resolution estimation of cyclic arrival rates
Ningyuan Chen, Donald K. K. Lee, Sahand Negahban
Exploiting the fact that most arrival processes exhibit cyclic behaviour, we propose a simple procedure for estimating the intensity of a nonhomogeneous Poisson process. The estima…
Sharp bounds on the variance in randomized experiments
Peter M. Aronow, Donald P. Green, Donald K. K. Lee
We propose a consistent estimator of sharp bounds on the variance of the difference-in-means estimator in completely randomized experiments. Generalizing Robins [Stat. Med. 7 (1988…
