The data. One can suggest Holiday impacts and identify lead and lag structure around these events. Se hela listan på analyticsvidhya.com One set of popular and powerful time series algorithms is the ARIMA class of models, which are based on describing autocorrelations in the data. ARIMA stands for Autoregressive Integrated Moving Average and has three components, p, d, and q, that are required to build the ARIMA model.

86-02. With ARIMA we are using the past values of every variable to make the predictions for the future. When we have multiple time series at our disposal, we can also extract information from their relationships, in this way VAR is a multivariate generalization of ARIMA because it is able to understand and use the relationship between several inputs. The multivariate generalization of the previous approach involves the adoption of the VAR model. VAR model extends the univariate autoregressive (AR) model by capturing the linear relations between multiple variables.
