In order to define formally the ATE, we define two potential outcomes : <math>y_{0}(i)</math> is the value of the outcome variable for individual <math>i</math> if they are not treated, <math>y_{1}(i)</math> is the value of the outcome variable for individual <math>i</math> if they are treated. For example, <math>y_{0}(i)</math>  is the health status of the individual if they are not administered the drug under study and <math>y_{1}(i)</math> is the health status if they are administered the drug.

为了正式定义 ATE,我们定义了两个潜在的结果: <math>y_{0}(i)</math > 是个体 <math> i </math> 没有被处理的结果变量的取值,<math> y _ {1}(i) </math> 是个体 <math> i </math> 被处理的结果变量的取值。例如,<math>y_{0}(i)</math > 是个体 <math> i </math> 没有注射研究药物的个体健康状态,<math>y_{1}(i)</math > 是个体 <math> i </math> 被注射药物的健康状态。
