A) If T denotes the number of observations, which of the following equations represents the one-step-ahead forecast for the model y<sub>t</sub> = β<sub>0</sub> + β<sub>1</sub>x<sub>t</sub> + ε<sub>t</sub>? A) <sub>T</sub><sub> - 1</sub> = b<sub>0 </sub>+ b<sub>1</sub>x<sub>T</sub><sub> - 1</sub> B) <sub> </sub> <sub> </sub> <sub>T</sub><sub> - 1</sub> = b<sub>0 </sub>+ b<sub>1</sub>x<sub>T + </sub><sub>1</sub> C) <sub>T</sub><sub> + 1</sub> = b<sub>0 </sub>+ b<sub>1</sub>x<sub>T</sub><sub>+1</sub> D) <sub>T</sub><sub> + 1 </sub>= b<sub>0</sub> - b<sub>1</sub>x<sub>T</sub><sub>+1</sub> T - 1 = b0 + b1xT - 1
B) If T denotes the number of observations, which of the following equations represents the one-step-ahead forecast for the model y<sub>t</sub> = β<sub>0</sub> + β<sub>1</sub>x<sub>t</sub> + ε<sub>t</sub>? A) <sub>T</sub><sub> - 1</sub> = b<sub>0 </sub>+ b<sub>1</sub>x<sub>T</sub><sub> - 1</sub> B) <sub> </sub> <sub> </sub> <sub>T</sub><sub> - 1</sub> = b<sub>0 </sub>+ b<sub>1</sub>x<sub>T + </sub><sub>1</sub> C) <sub>T</sub><sub> + 1</sub> = b<sub>0 </sub>+ b<sub>1</sub>x<sub>T</sub><sub>+1</sub> D) <sub>T</sub><sub> + 1 </sub>= b<sub>0</sub> - b<sub>1</sub>x<sub>T</sub><sub>+1</sub> T - 1 = b0 + b1xT + 1
C) If T denotes the number of observations, which of the following equations represents the one-step-ahead forecast for the model y<sub>t</sub> = β<sub>0</sub> + β<sub>1</sub>x<sub>t</sub> + ε<sub>t</sub>? A) <sub>T</sub><sub> - 1</sub> = b<sub>0 </sub>+ b<sub>1</sub>x<sub>T</sub><sub> - 1</sub> B) <sub> </sub> <sub> </sub> <sub>T</sub><sub> - 1</sub> = b<sub>0 </sub>+ b<sub>1</sub>x<sub>T + </sub><sub>1</sub> C) <sub>T</sub><sub> + 1</sub> = b<sub>0 </sub>+ b<sub>1</sub>x<sub>T</sub><sub>+1</sub> D) <sub>T</sub><sub> + 1 </sub>= b<sub>0</sub> - b<sub>1</sub>x<sub>T</sub><sub>+1</sub> T + 1 = b0 + b1xT+1
D) If T denotes the number of observations, which of the following equations represents the one-step-ahead forecast for the model y<sub>t</sub> = β<sub>0</sub> + β<sub>1</sub>x<sub>t</sub> + ε<sub>t</sub>? A) <sub>T</sub><sub> - 1</sub> = b<sub>0 </sub>+ b<sub>1</sub>x<sub>T</sub><sub> - 1</sub> B) <sub> </sub> <sub> </sub> <sub>T</sub><sub> - 1</sub> = b<sub>0 </sub>+ b<sub>1</sub>x<sub>T + </sub><sub>1</sub> C) <sub>T</sub><sub> + 1</sub> = b<sub>0 </sub>+ b<sub>1</sub>x<sub>T</sub><sub>+1</sub> D) <sub>T</sub><sub> + 1 </sub>= b<sub>0</sub> - b<sub>1</sub>x<sub>T</sub><sub>+1</sub> T + 1 = b0 - b1xT+1
