Such variables zil are called instrumental vari-ables or instruments. If there are enough good such instruments, we can estimate the causal effect of the regressor on the dependent variable.

Mar 25, 2025 · We explain key instrumental variables assumptions, interpret instrumental variables estimates in clinical settings, and demonstrate the use of diagnostic tools.

Naive supervised learning can fail catastrophically due to confounders. Probabilistic counterfactuals are possible with persistent confounders. Instrumental variables allow counterfactual inference when …
