High dimensional asymptotics of likelihood ratio tests in the Gaussian sequence model under convex constraints

Qiyang Han, Bodhisattva Sen, Yandi Shen

In the Gaussian sequence model $Y = μ + ξ$ , we study the likelihood ratio test (LRT) for testing $H_{0} : μ = μ_{0}$ versus $H_{1} : μ \in K$ , where $μ_{0} \in K$ , and $K$ is a closed convex set in…

On a phase transition in general order spline regression

Yandi Shen, Qiyang Han, Fang Han

In the Gaussian sequence model $Y = θ_{0} + ε$ in $R^{n}$ , we study the fundamental limit of approximating the signal $θ_{0}$ by a class $Θ (d, d_{0}, k)$ of (generalized) s…

Exponential inequalities for dependent V-statistics via random Fourier features

Yandi Shen, Fang Han, Daniela Witten

We establish exponential inequalities for a class of V-statistics under strong mixing conditions. Our theory is developed via a novel kernel expansion based on random Fourier featu…
