Consider the heteroscedastic nonparametric regression model … where $ta=V_0(X)^{1/2}ta^{\star}$, $ta^{\star}$ is bounded almost surely, and satisfies…

Fourier–Hahn–Lévy conjecture. If $f:\mathbb{Z}\to\mathbb{Z}$ is tractable, then the $f$-moment can be estimated to within a constant factor with a Lévy-Tower, either directly or af…

For a function $f$, its $f$-moment is the quantity … A function is tractable if its moment can be estimated to within a constant factor using a small sketch. Lévy–Khintchine repres…

For a function $f$ on the frequency domain, an $f$-moment is the quantity … A function is tractable if its moment can be estimated to within a constant factor using…
