In this research, use the time series models to Create Arima Model Gross domestic product (GDP) at current price Petroleum Refining 2010 – 2022.
The results showed that the model is the appropriate model for the series of Arima Model Gross domestic product (GDP) at current price Petroleum Refining is :ARIMA (0,1,0)
According to the estimation results of this model, we observe the compatibility between observed and estimated values as these values are consistent with those in the original time series, indicating the strength of the model and predictability.
