Statistics Paper Reveals New Lower Bound Results

lihua_lei_stat · x · 2026-07-17

This post discusses findings from a statistics paper where the author notes their obtained lower bound is q sqrt{log(1/q)}, a surprisingly unexpected form.

They compare this to @weijie444's FDR linking theorem, which provides an upper bound on the order of log(1/q). However, the properties differ: the latter applies to more general non-Gaussian scenarios, whereas these results are specifically tied to Gaussian settings.

A reply adds that if q is allowed to approach 0, they have proven supn C(n) = infty and derived stronger rate conclusions. The paper has been submitted to arXiv and will be published the next day.
