ARIMA is a form of regression analysis that indicates the strength of a dependent variable relative to other changing variables. The final objective of the model is to predict future time series movement by examining the differences between values in the series instead of through actual values .

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 best for forecasting?
ARIMA (Autoregressive Integrated Moving Average): ARIMA is arguably the most popular and widely used statistical technique for forecasting .
Read moreWhat is Time series analysis in data science?
Time series analysis is a specific way of analyzing a sequence of data points collected over an interval of time . In time series analysis, analysts record data points at consistent intervals over a set period of time rather than just recording the data points intermittently or randomly.
Read moreWhat is forecasting in data science?
Forecasting is to predict or estimate (a future event or trend). For businesses and analysts forecasting is determining what is going to happen in the future by analyzing what happened in the past and what is going on now .
Read moreWhat are time series forecasting models?
Time series forecasting occurs when you make scientific predictions based on historical time stamped data . It involves building models through historical analysis and using them to make observations and drive future strategic decision-making.
Read moreWhich model is used for time series data?
As for exponential smoothing, also ARIMA models are among the most widely used approaches for time series forecasting. The name is an acronym for AutoRegressive Integrated Moving Average. In an AutoRegressive model the forecasts correspond to a linear combination of past values of the variable.3 Eki 2019
