NettetLinear regression is cheap. Doing two linear regressions for each pair of smoothing splines, instead of just one, may yield faster convergence. Once we have the partial residuals based on both the ordinary regressors and the two smoothing splines, we start all over again. ESL suggests that it is computationally desirable to renormalize the f˜ http://qed.econ.queensu.ca/pub/faculty/mackinnon/econ882/slides/econ882-2024-slides-14.pdf

NettetKey Ideas of DDML Key Ideas of DDML Suppose we want to estimate the partially linear regression, or PLR, model, y i = βd i +g(x i)+u i (1) where d i is a “treatment” variable, but not one that is assigned at random, and x i is a vector that contains p control variables. We want to obtain an estimate of β and make inferences about it.
