Analyze another fileStandard-library analysis: what is the causal effect when the treatment is confounded? Map an outcome, a confounded treatment, and at least one instrument — a variable that shifts the treatment but has no other route to the outcome — and get two-stage least squares built stage by stage: the first-stage F on the excluded instruments and the instrument-strength verdict it implies, the ordinary least squares estimate and the instrumented estimate side by side with the difference between them made explicit, an over-identification (Sargan) test when more than one instrument is supplied, an endogeneity (Wu-Hausman) test, and a plain statement of the exclusion restriction the whole estimate rests on.
