2.Which of following statement is NOT correct about p: %3D = pe-1 + U a. As p approaches one in absolute value, the value of the previous observation of the error term becomes more important in determining the current value of error shock and a high degree of serial correlation exists. b. if p is greater than one in absolute value is unreasonable because it implies that the error term tends to continually increase in absolute value over time ("explode"). c. if Ipl s 1, then e, is stationary d. none of above

2.Which of following statement is NOT correct about p:
E = pe-1 + u
a. As p approaches one in absolute value, the value of the previous observation of the error
term becomes more important in determining the current value of error shock and a high
degree of serial correlation exists.
b. if p is greater than one in absolute value is unreasonable because it implies that the error
term tends to continually increase in absolute value over time ("explode").
c. if Ipl < 1, then e, is stationary
d. none of above
