Local Polynomial Estimation
A class of estimation methods in nonparametric regression that estimate function values by fitting a local polynomial in the neighborhood of a target point. It is used for nonparametric estimation problems such as CATE.

When using kernel methods or local polynomial estimation for CATE, the local structure of the covariate distribution (such as spikes, discontinuities or irregular clustering) is directly reflected in the convergence behavior of the estimator.
