Retail Forecast
This project forecasts the turnover rate of Western Australia's retail sector from 2015 to 2017 base on historical data from 1982 to 2015 using ARIMA models and ETS models.
Although the Covid-19 pandemic introduced unexpected disturbances, the final model still successfully captured the pattern of turnover recover in the post-pandemic era.
