You have time series xt recorded for 20 time steps (years). You want to predict the data for 3 years in the future. You've decided to use drift forecasting. a) What is the formula for predicted value for 3 years in future? b) The predicted value for the 5 year in the future? What is the difference between this value and value estimated in the question a)? c) Is the drift method applicable if the inputs and output are the crossectional data?
