R naive forecast

WebDescription. naive is the model constructor for a random walk model applied to y . This is equivalent to an ARIMA (0,1,0) model. naive () is simply a wrapper to maintain forecast package similitude. seasonal returns the model constructor for a seasonal random walk equivalent to an ARIMA (0,0,0) (0,1,0)m model where m is the seasonal period. WebThe forecasting process proceeds as follows: (i) first the data are seasonally adjusted; (ii) then forecasts are generated for the seasonally adjusted data via linear exponential smoothing; and (iii) finally the seasonally adjusted forecasts are "reseasonalized" to obtain forecasts for the original series. The seasonal adjustment process is ...
