When using simple exponential smoothing,the value of the smoothing constant $\alpha$ cannot be:
A)Negative
B)Greater than zero
C)Greater than 1
D).99
E)Both A and C

Question

Quizplus · Accepted Answer

The value of the smoothing constant α must be between 0 and 1, inclusive. Therefore, it cannot be negative (option A) or greater than 1 (option C). Option D is a valid value for α, and option B is true but incomplete (it should be "greater than zero and less than or equal to 1"). Thus, the correct answer is option E.
