What is the formula used to calculate the value of b t in the linear trend equation Ft +k = at + btk while using double exponential smoothing?
Homework Answers
at = aFt +(1-
)(at-1+bt-1)
The liner trend equation is the sum of 2 parts in the double exponential smoothing and the forecast is this sum. The sum which gives the forecast is at+btK where at gives the intercept of y at time t and bt gives the slope at time t
