Nonparametric Estimation of Path-specific Effects in Presence of Nonignorable Missing Covariates
Jiawei Shan, Ting Wang, Wei Li +1
The path-specific effect (PSE) is of primary interest in mediation analysis when multiple intermediate variables between treatment and outcome are observed, as it can isolate the s…
