Transportability of Regression Calibration with External Validation Studies for Measurement Error Correction
Zexiang Li, Donna Spiegelman, Molin Wang +2
In nutritional and environmental epidemiology, exposures are impractical to measure accurately, while practical measures for these exposures are often subject to substantial measur…
Exposure measurement error correction in longitudinal studies with discrete outcomes
Ce Yang, Ning Zhang, Jiaxuan Li +4
Environmental epidemiologists are often interested in estimating the effect of time-varying functions of the exposure history on health outcomes. However, the individual exposure m…
Statistical methods for cost-effectiveness analysis of left-truncated censored survival data with treatment delays
Polyna Khudyakov, Li Xu, Ce Yang +2
The incremental cost-effectiveness ratio (ICER) and incremental net benefit (INB) are widely used for cost-effectiveness analysis. We develop methods for estimation and inference f…
Improving Transportability of Regression Calibration Under the Main/External Validation Study Design
Zexiang Li, Donna Spiegelman, Molin Wang +2
In epidemiology, obtaining accurate individual exposure measurements can be costly and challenging. Thus, these measurements are often subject to error. Regression calibration with…
Measurement Error Correction for Spatially Defined Environmental Exposures in Survival Analysis
Lin Ge, Ce Yang, David Zucker +3
Environmental exposures are often defined using buffer zones around geocoded home addresses, but these static boundaries can miss dynamic daily activity patterns, leading to biased…
