Introduction to ARIMA Models for Newbies

(S'ouvre dans une nouvelle fenêtre)

ARIMA (short for AutoRegressive Integrated Moving Average) is a technique for time series analysis and forecasting. It is one of the most widely used approaches for time series forecasts. There are seasonal and non-seasonal ARIMA models, depending on the type of time series data.

ARIMA models are often used in the financial industry. They are fundamental to understanding time series analysis. In addition, ARIMA models can be very complex, which means that they are not always easy to understand.

In this tutorial, we would like to give you an easy-to-understand and visual introduction to ARIMA models.
