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…
On the Individual Surrogate Paradox
Linquan Ma, Yunjian Yin, Lan Liu +1
When the primary outcome is difficult to collect, surrogate endpoint is typically used as a substitute. It is possible that for every individual, treatment has a positive effect on…
