WebAug 3, 2024 · We have tried to introduce the binary auxiliary variables for each set of constraints and finally linking these constraints with whose specific binary variable. This approach seems to work fine, but I am facing that we will have to use the product of the binary and continuous variables. I knew that we can use specific linearization to do this. WebIn the special case when we have a binary auxiliary variable Z 2f0;1g, we obtain the following estimator: E[YjZ= 1] E[YjZ= 0] E[DjZ= 1] E[DjZ= 0]: This is the classical Wald estimator. A number of the treatment e ect estimators we consider below take this form, for di erent choices of the auxiliary variable Z. high court purple
