Chapter 21: Clarification of the XLearner diagram #334

Closed zhuivv closed 1 year ago

zhuivv commented 1 year ago

The notation in the diagram under XLearner in Chapter 21 is unclear. In the second stage, could you specify what is $Y^$? It is not easy to connect $Y|T=1$ with the previous equation $M_1(X,T=0)$.

Thanks for any clarification!
