Note on Causal Inference for the Brave and True

2023/09/07

01 - Introduction to Causality

  • When Association IS Causation
    • Y0i is the potential outcome for unit i without treatment
    • Y1i is the potential outcome for the same unit i with the treatment
    • Y1i - Y0i is the potential outcomes of individual treatment effect
    • Average Treatment Effect (ATE) = E[Y1 - Y0]
    • Average Treatment effect on the Treated (ATT) = E[Y1 - Y0 T = 1]

E[600 + 750] - E[500 + 600] = E[600 + 750] - E[500 + 600]
