ARIMA uses a number of lagged observations of time series to forecast observations . A weight is applied to each of the past term and the weights can vary based on how recent they are. AR(x) means x lagged error terms are going to be used in the ARIMA model. ARIMA relies on AutoRegression.

ARIMA models are not generally preferred over any other time series analysis method . There are certainly not preferred when the series demonstrate non-stationaries unable to be modelled using the ARIMA framework.
Read moreWhat is ARIMA in machine learning?
ARIMA is an acronym for “autoregressive integrated moving average .” It’s a model used in statistics and econometrics to measure events that happen over a period of time. The model is used to understand past data or predict future data in a series.
Read moreWhy is the ARIMA model good?
It is widely used in demand forecasting, such as in determining future demand in food manufacturing. That is because the model provides managers with reliable guidelines in making decisions related to supply chains . ARIMA models can also be used to predict the future price of your stocks based on the past prices.

ARIMA (1,1,33) model showed better accuracy. Although within the measurement of MAPE, the accuracy was 99.74% and ARIMA (1,2,33) was 99.75% which is almost the same. However, owing to its result from holdout test it is considered the best accuracy among the three models.
Read moreIs ARIMA good for long term forecasting?
The ARIMA models have proved to be excellent short-term forecasting models for a wide variety of time series.
