Before revision:  Our method is based on a sequential regression peeling process, which we show can be equivalently interpreted as a Neyman orthogonal moment estimator.
After revision:  These structural parameters can be used for off-policy evaluation of any target dynamic policy at parametric rates, subject to semi-parametric restrictions on the data generating process. Our work is based on a sequential regression peeling process, which we show can be equivalently interpreted as a Neyman orthogonal moment estimator.
