Why this lab Build a series from trend, seasonality, and noise, and see what each part carries.
A time series can combine a long-run direction, repeating cycles, and irregular variation. Adjust each component, then reconstruct a target pattern instead of guessing from vocabulary.
Additive model\(y_t=T_t+S_t+e_t\)Use an additive view when seasonal swings remain roughly constant in size.
