question 50

Multiple Choice

Consider a regression with two variables, in which X_1i is the variable of interest and X_2i is the control variable. Conditional mean independence requires

• A)E(u_i|X_1i, X_2i)= E(u_i|X_2i)
• B)E(u_i|X_1i, X_2i)= E(u_i|X_1i)
• C)E(u_i|X_1i)= E(u_i|X_2i)
• D)E(u_i)= E(u_i|X_2i)
