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 moreIs ARIMA an algorithm?
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.
Read moreWhen can ARIMA model be used?
ARIMA models are applied in some cases where data show evidence of non-stationarity in the sense of mean (but not variance/autocovariance) , where an initial differencing step (corresponding to the “integrated” part of the model) can be applied one or more times to eliminate the non-stationarity of the mean function ( …

Read moreHow does ARIMA model work?
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.
