Inference and FDR Control for Simulated Markov Random Fields in High-dimension

no code implementations11 Feb 2022 Haoyu Wei, Xiaoyu Lei, Huiming Zhang

We further propose a decorrelated score test based on the decorrelated score function and prove the asymptotic normality of the score function without the influence of many nuisance parameters under the assumption that it accelerates the convergence of the MCMC method.

Asymptotic in a class of network models with an increasing sub-Gamma degree sequence

no code implementations2 Nov 2021 Jing Luo, Haoyu Wei, Xiaoyu Lei, Jiaxin Guo

For the differential privacy under the sub-Gamma noise, we derive the asymptotic properties of a class of network models with binary values with a general link function.

Heterogeneous Overdispersed Count Data Regressions via Double Penalized Estimations

no code implementations7 Oct 2021 Shaomin Li, Haoyu Wei, Xiaoyu Lei

This paper studies the non-asymptotic merits of the double $\ell_1$-regularized for heterogeneous overdispersed count data via negative binomial regressions.


Non-asymptotic Optimal Prediction Error for Growing-dimensional Partially Functional Linear Models

no code implementations10 Sep 2020 Huiming Zhang, Xiaoyu Lei

From the non-asymptotic point of view, we focus on the rate-optimal upper and lower bounds of the prediction error.
