- Scott and Varian modeled the data in Figure 1 using a structural
**time****series**with three state components: a trend μ t, a seasonal pattern τ t and a regression component β T x t. The model is. y t = μ t + τ t + β T x t + ϵ t. μ t + 1 = μ t + δ t + η 0 t. δ t + 1 = δ t + η 1 t. τ t + 1 = − ∑ s = 1 S − 1 τ t + η 2 t. - When we track a certain variable over an interval of

- Selecting the model. Due to seasonality involved, simple models will not be able to capture it. We therefore use the seasonal ARIMA and exponential smoothing models. Exponential smoothing models have seasonality built in it by construction. Complex models like mixed models and neural nets will be an overkill. # simple plot to see seasonality ...
