Nonparametric inference about mean functionals of nonignorable nonresponse data without identifying the joint distribution
Wei Li, Wang Miao, Eric Tchetgen Tchetgen
We consider identification and inference about mean functionals of observed covariates and an outcome variable subject to nonignorable missingness. By leveraging a shadow variable,…
Adaptive Estimation of Nonparametric Functionals
Lin Liu, Rajarshi Mukherjee, James Robins +1
We provide general adaptive upper bounds for estimating nonparametric functionals based on second order U-statistics arising from finite dimensional approximation of the infinite d…
On Varieties of Doubly Robust Estimators Under Missingness Not at Random With a Shadow Variable
Wang Miao, Eric Tchetgen Tchetgen
Suppose we are interested in the mean of an outcome variable missing not at random. Suppose however that one has available a fully observed shadow variable, which is associated wit…
Lepski's Method and Adaptive Estimation of Nonlinear Integral Functionals of Density
Rajarshi Mukherjee, Eric Tchetgen Tchetgen, James Robins
We study the adaptive minimax estimation of non-linear integral functionals of a density and extend the results obtained for linear and quadratic functionals to general functionals…
