Two graphical criteria for estimating causal effectsThis is the 4th article in a series on causal effects. In the last article of this series, we explored the question of identifiability. In other words, can the causal effect be evaluated from the given data? There we saw a systematic 3-step process to express any causal effect given a causal model where all variables are observed. The problem, however, becomes much more interesting when we have unmeasured confounders. In this article, I discuss two quick-and-easy…
