Vector Autoregressive Models for Multivariate Time Series | Springer Nature Link
The vector autoregression (VAR) model is one of the most successful, flexible, and easy to use models for the analysis of multivariate time series. It is a natural extension of the univariate autoregressive model to dynamic multivariate time series.

Vector Autoregression (VAR) for Multivariate Time Series - GeeksforGeeks
May 14, 2024 - VAR models acquired significant momentum in econometrics and macroeconomics during the 1970s and 1980s. Vector Autoregression (VAR) is a multivariate extension of autoregression (AR) models.
ELI5: Vector Autoregression for Multivariate Time Series?
In the VAR class of models, you move beyond the single equation. You'll have more than one response variable of interest and you probably have to consider interactions and feedback loops between the equations.
.
One will benefit from being careful when selecting the lag-length. The parameter estimates aren't readily interpretable. Instead, one oftentimes interpret what is known as the impulse-response function. There are quite a few estimation methods available. For example, some practitioners use the Generalized Method of Moments, others lean towards Bayesian Autoregression. The different methods have their merits and drawbacks which you'll have to consider given your application. On a side note, if I remember correctly, the number of parameters to be estimated in an unrestricted VAR model equals the number of equations, squared.
.
What is more is that the VAR class of models is fairly well suited for predictive modeling.

March 29, 2021Beginner: Help with vector autoregression
Given that you understand what a vector autoregression is I would do it in the following steps: First check the integration order of your variables. If all are I(0) (I doubt it) go to 2.1), if they are I(1) check for cointegration, if cointegrated, go to 2.2), if there are no cointegrating relationships, difference data and go to 2.1) 2.1) fit the VAR according to your information criteria 2.2) fit VECM according to your information criteria 3) check the residuals for independence and normality, if it doesn't seem like a good fit, go back to 2.1) / 2.2) and try the next best lag according to the criteria you chose.

April 26, 2013[Q] Vector Autoregressive Model vs linear regression for time series?
I think so. The possibility of feedback loops is a big reason to consider VAR. And part of the steps behind VAR may provide further support for that (e.g., Granger causality tests). And probably you should check some variations. You seem to have a panel, so you could check PVAR, for example. More on reddit.com

Chapter 3: Vector Autoregressive Methods — Time Series Analysis Handbook
We learned that stationarity is a condition that is necessary when using ARIMA while this need not be imposed when using the linear regression model. In this notebook, we extend the forecasting problem to a more generalized framework where we deal with multivariate time series–time series which has more than one time-dependent variable. More specifically, we introduce vector autoregressive (VAR) models and show how they can be used in forecasting mutivariate time series.

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.
