Hybrid hyperinterpolation over general regions
Congpei An, Jiashu Ran, Alvise Sommariva
We present an -regularized discrete least squares approximation over general regions under assumptions of hyperinterpolation, named hybrid hyperinterpolation. Hybr…
Hard thresholding hyperinterpolation over general regions
Congpei An, Jiashu Ran
This paper proposes a novel variant of hyperinterpolation, called hard thresholding hyperinterpolation. This approximation scheme of degree leverages a hard thresholding operat…
Inference for natural mediation effects under case-cohort sampling with applications in identifying COVID-19 vaccine correlates of protection
David Benkeser, Iván Díaz, Jialu Ran
Combating the SARS-CoV2 pandemic will require the fast development of effective preventive vaccines. Regulatory agencies may open accelerated approval pathways for vaccines if an i…
Nonparametric inference for interventional effects with multiple mediators
David Benkeser
Understanding the pathways whereby an intervention has an effect on an outcome is a common scientific goal. A rich body of literature provides various decompositions of the total i…
