\small (e) Finally, one can check that the function u(x, y) defined by the above expression is harmonic in the strip, and converges uniformly to f_0(x) as y \to 0, and to f_1(x) as y \to 1. Moreover, one sees that u(x, y) vanishes at infinity, that is, \lim_{\ver...
Denoting the first intervention by do(X = 1) and the second by do(X = 0), our task is to estimate the difference which is known as the “causal effect difference,” or “average causal effect” (ACE). 对于离散的随机变量,可以表示为,E(Y|do(X=1))-E(Y|do(X=0)) \\ ...
