Deterministic seasonality
WebSo, which approach should we use to accommodating seasonality: differencing or deterministic functions of time? There is a seasonal Augmented Dickey Fuller test that will help us decide. In this case, none of the listed p-values are significant at any listed lags, so a difference is clearly indicated. WebWhile there is consensus on the importance of seasonality, there is little agreement on its treatment. Indeed, there are several ways to handle seasonality, each implicitly making different assumptions about the process, namely, as if it is • a purely deterministic seasonal process, • a stationary seasonal process, or • an integrated ...
