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.

ARIMA, short for ‘AutoRegressive Integrated Moving Average’, is a forecasting algorithm based on the idea that the information in the past values of the time series can alone be used to predict the future values.

An ARIMA model is basically an ARMA model fitted on d-th order differenced time series such that the final differenced time series is stationary . A stationary time series is one whose statistical properties such as mean, variance, autocorrelation, etc. are all constant over time.

Autoregressive Integrated Moving Average Model. An ARIMA model is a class of statistical models for analyzing and forecasting time series data . It explicitly caters to a suite of standard structures in time series data, and as such provides a simple yet powerful method for making skillful time series forecasts.9 Oca 2017
Read moreIs ARIMA Good for forecasting?
The ARIMA model is becoming a popular tool for data scientists to employ for forecasting future demand , such as sales forecasts, manufacturing plans or stock prices. In forecasting stock prices, for example, the model reflects the differences between the values in a series rather than measuring the actual values.
