Vector autoregression - Wikipedia
July 25, 2026 - Vector autoregression (VAR) is a statistical model used to capture the relationship between multiple quantities as they change over time. VAR is a type of stochastic process model. VAR models generalize the single-variable (univariate) autoregressive model by allowing for multivariate time series.

If the series are stationary, we forecast them by fitting a VAR to the data directly (known as a “VAR in levels”). If the series are non-stationary, we take differences of the data in order to make them stationary, then fit a VAR model (known as a “VAR in differences”).

The VAR class assumes that the passed time series are stationary. Non-stationary or trending data can often be transformed to be stationary by first-differencing or some other method. For direct analysis of non-stationary time series, a standard stable VAR(p) model is not appropriate.

Why Is the Vector Autoregressive Model One Of The Best For Time-series Forecasting? | by Aliyu Jimoh | Medium
December 14, 2023 - The Vector Autoregressive (VAR) model is a superstar in the world of time-series forecasting, especially when dealing with multiple data streams simultaneously. Think of it as a tool that doesn’t just look at one thing at a time, but considers several related elements together.

July 3, 2025 - How do you check for stationarity in this model? Well, usually practitioners find the order of integration of each time series separately. So you need to do the following: Apply, e.g., an ADF to each time series separately. Find for each time series its “d” order of integration. Difference the time series as per its corresponding “d” order of integration. Use the differenced data to estimate your VAR model.

On the other hand, a multivariate time series has more than one time-dependent variable. For a multivariate process, several related time series are observed simultaneously over time. As an extension of the univariate case, the multivariate time series model involves two or more input variables, and leverages the interrelationship among the different time series variables.
