I have researched all over the text books and software (R/SAS/SPSS), but I have not encountered Simple Exponential Smoothing (SES) with a drift ?
Is it possible to add a drift term to Simple exponential smoothing, so that SES captures the direction of the trend? If yes, how is this implemented in software like
forecast package in
R or any other software?
Also, is SES with drift equivalent to ARIMA(0,1,1) + Drift ?
