The 2SLS estimator of causal_iv_fit_2sls() is consistent when IV conditions hold. This wrapper gives a classical Cinelli-Hazlett envelope treating the 2SLS estimate AS IF it were a backdoor OLS estimate. This is a conservative sensitivity check: the IV effect is bias-adjusted against a hypothetical remaining confounder U that affects BOTH the exposure and the outcome after the instruments have been projected out. It is the right envelope to report alongside the Sargan test.

Usage

causal_sensitivity_from_iv(fit, q = 1, alpha = 0.05)

Arguments

fit: An edaphos_causal_iv object.
q, alpha: See causal_sensitivity_summary().

Value

List identical to causal_sensitivity_summary() with an extra fit_estimator field.
