Linear-cost unbiased estimator for large crossed random effect models via couplings

Paolo Ceriani and Giacomo Zanella / 2023-09-27

In the following we show how it is possible to obtain parallelizable, unbiased and computationally cheap estimates of Crossed random effects models with a linear cost in the number of datapoints (and paramaters) exploiting couplings. […] CREM model a continuous response variables \(Y\) as…

Inference on Adaptively Collected Data

Ruohan Zhan / 2022-10-11

It is increasingly common for data to be collected adaptively, where experimental costs are reduced progressively by assigning promising treatments more frequently. However, adaptivity also poses great challenges on post-experiment inference, since observations are dependent, and standard estimates…

Non-Homogeneous Poisson Process Intensity Modeling and Estimation using Measure Transport

Tin Lok James Ng / 2022-09-19

A NHPP defined on \({\cal S} \subset \mathbb{R}^{d}\) can be fully characterized through its intensity function \(\lambda: {\cal S} \rightarrow [0, \infty)\). We present a general model for the intensity function of a non-homogeneous Poisson process using measure transport. The model finds its roots…
