Unobservable Selection and Coefficient Stability
Updated Tue, 04 Feb 2020 00:13:34 +0000
The function implements the method of (*) for evaluating robustness to omitted variable bias.
Specifically, it implements Proposition 2, Corollary 1 and Proposition 3. The implementation relies upon Matlab's fitlm(). Examples included for both computing the (a) bias-adjusted treatment
effect and (b) the delta value (bound) to match a given treatment effect, for the unrestricted estimator under additional (unrelated) controls. The complete documentation is within the function oster.mat.
