A company's monthly demand has a repeating annual seasonal pattern. Its average demand increases significantly over several years, but the absolute magnitude of seasonal variations remains nearly unchanged.

Assertion (A): Additive seasonality may be more suitable than multiplicative seasonality.

Reason (R): Multiplicative seasonality is generally appropriate when seasonal effects change proportionally with the series level.

A retail store experiences a steady upward trend in demand. The manager uses Simple Exponential Smoothing with α = 0.9 and observes that the fitted values closely follow recent demand.

Assertion (A): Increasing α sufficiently allows SES to model a persistent upward trend in the same way as Holt’s model.

Reason (R): A larger α increases the influence of the most recent observation on the updated level estimate.

Choose the correct option.

Consider the following practices when comparing SES, Holt and Holt-Winters models on monthly warehouse shipment data.

I. Using chronological training and testing periods preserves the forecasting order.

II. A model with lower training RMSE must also have lower test RMSE.

III. A model with lower MAE can nevertheless have higher RMSE than another model.

IV. Seasonality should be determined entirely by whichever model has the most parameters.

Choose the correct combination.
