Keep in mind the following assumptions when conducting causal inference: 1, unit i receiving treatment will not affect other units outcome, i.e., no network effect, 2, if unit i is in the treatment group, the treatment it receives is the same as all other units in the treatment group, i.e., only one version of the treatment. Endogeneity arose when the independent variable X (treatment) is correlated with the error term in a regression, thus biases the estimation (treatment effect on the outcome variable Y). what data must be collected to support causal relationships.
