Here you’ll find everything about ARIMA models, whether it’s tutorials on implementing an ARIMA model in Python or conceptual articles.
An ARIMA (AutoRegressive Integrated Moving Average) model is a type of statistical model that is commonly used for time series forecasting. It is a generalization of the popular ARMA model, which only considers the autoregressive and moving average components. ARIMA models are particularly useful for time series data with strong seasonal patterns. It is a combination of three different types of models: an autoregressive (AR) model, an integrated (I) model, and a moving average (MA) model. The AR component of the model captures the autocorrelation in the data, which is the tendency for the value of the time series at a given time to correlate with its past values. The I component of the model accounts for the non-stationarity of the data. This means that the mean and variance of the time series are not constant over time. The MA component of the model captures the error in the data. This is the difference between the actual value and the predicted value of the time series.
