The Population Multiple Regression Model When There Are Two Regressors $\sum _ { j = 0 } ^ { 2 } \beta _ { j }$

Multiple Choice

The population multiple regression model when there are two regressors, X_1i and X_2i can be written as follows, with the exception of:

A) Y_i = ?₀ + ?₁X_1i + ?₂X_2i + u_i, i = 1,..., n
B) Y_i = ?₀X_0i + ?₁X_1i + ?₂X_2i + u_i, X_0i = 1, i = 1,..., n
C) Y_i = $\sum _ { j = 0 } ^ { 2 } \beta _ { j }$ X_ji + u_i, i = 1,..., n
D) Y_i = ?₀ + ?₁X_1i + ?₂X_2i + ... + ?_kX_ki + u_i, i = 1,..., n
