Model Selection and Forecasting

The assignment content presents an analysis of a transformer's sales data using different models, including AR, MA, and ARMA. The results show that the MA model performed better than the AR model in predicting future sales, as it captures both trend and seasonality in the historical data. Additionally, the AR(1) and AR(2) models were found to be insignificant when added to the MA model. The best forecast model is the MA model, which can be used for making predictions.
