Deterministic seasonality
WebNov 8, 2024 · Deterministic seasonality functions and stochastic processes The actual DAT is also conditioned by the recent temperature behavior. In addition to the deterministic component, DAT models should include a specific stochastic component, which we will assume follows mean-reversion dynamics (Dornier & Queruel, 2000 ).

WebJan 1, 1998 · If the test is performed with seasonal deterministic dummy vari- ables included, then the results can be used to deter- mine whether dummy variables capture all aspects of seasonality. If seasonal dummy variables are in- cluded and unit root cannot be rejected, then stan- dard dummy variables will not capture a changing seasonal trend. 4.
