Semiparametric Efficient Dimension Reduction in multivariate regression with an Inner Envelope

Linquan Ma, Hyunseung Kang, Lan Liu

Recently, Su and Cook proposed a dimension reduction technique called the inner envelope which can be substantially more efficient than the original envelope or existing dimension…

Mixed Effects Envelope Models

Yuyang Shi, Linquan Ma, Lan Liu

When multiple measures are collected repeatedly over time, redundancy typically exists among responses. The envelope method was recently proposed to reduce the dimension of respons…

Envelopes for multivariate linear regression with linearly constrained coefficients

Dennis Cook, Liliana Forzani, Lan Liu

A constrained multivariate linear model is a multivariate linear model with the columns of its coefficient matrix constrained to lie in a known subspace. This class of models inclu…

Regression-based Negative Control of Homophily in Dyadic Peer Effect Analysis

Lan Liu, Eric Tchetgen Tchetgen

A prominent threat to causal inference about peer effects over social networks is the presence of homophily bias, that is, social influence between friends and families is entangle…

Doubly Robust Estimation in Observational Studies with Partial Interference

Lan Liu, Michael G. Hudgens, Bradley Saul +3

Interference occurs when the treatment (or exposure) of one individual affects the outcomes of others. In some settings it may be reasonable to assume individuals can be partitione…
