Inference for local parameters in convexity constrained models
Hang Deng, Qiyang Han, Bodhisattva Sen
We consider the problem of inference for local parameters of a convex regression function based on observations from a standard nonparametric regression…
On a phase transition in general order spline regression
Yandi Shen, Qiyang Han, Fang Han
In the Gaussian sequence model in , we study the fundamental limit of approximating the signal by a class of (generalized) s…
Confidence intervals for multiple isotonic regression and other monotone models
Hang Deng, Qiyang Han, Cun-Hui Zhang
We consider the problem of constructing pointwise confidence intervals in the multiple isotonic regression model. Recently, [HZ19] obtained a pointwise limit distribution theory fo…
Complex sampling designs: uniform limit theorems and applications
Qiyang Han, Jon A. Wellner
In this paper, we develop a general approach to proving global and local uniform limit theorems for the Horvitz-Thompson empirical process arising from complex sampling designs. Gl…
Limit distribution theory for block estimators in multiple isotonic regression
Qiyang Han, Cun-Hui Zhang
We study limit distributions for the tuning-free max-min block estimator originally proposed in [FLN17] in the problem of multiple isotonic regression, under both fixed lattice des…
Isotonic regression in general dimensions
Qiyang Han, Tengyao Wang, Sabyasachi Chatterjee +1
We study the least squares regression function estimator over the class of real-valued functions on that are increasing in each coordinate. For uniformly bounded signals…
