Doubly Robust Estimators of Quantile Treatment Effects With Semiparametric Cumulative Probability Models
Hao Wu, Chun Li, Bryan E. Shepherd
The paper proposes doubly robust semiparametric methods based on cumulative probability models to estimate quantile treatment effects and related distributional measures, providing…
Addressing errors in multiple variables using generalized raking and cumulative probability models
Eric S. Kawaguchi, Chun Li, Frank E. Harrell +3
Routinely collected data, such as electronic health record (EHR) data, are frequently used for biomedical research, but these data are prone to errors, which can bias study finding…
Between- and Within-Cluster Spearman Rank Correlations
Shengxin Tu, Chun Li, Bryan E. Shepherd
Clustered data are common in practice. Clustering arises when subjects are measured repeatedly, or subjects are nested in groups (e.g., households, schools). It is often of interes…
Probability-scale residuals for event-time data
Eric S. Kawaguchi, Bryan E. Shepherd, Chun Li
The probability-scale residual (PSR) is defined as , where is the observed outcome and is a random variable from the fitted distribution. The PSR is pa…
