Why we use VAR model?

Forecasts from VAR models are quite flexible because they can be made conditional on the potential future paths of specified variables in the model. In addition to data description and forecasting, the VAR model is also used for structural inference and policy analysis.

What is a structural VAR model?

Abstract: Structural Vector Autoregressions (SVARs) are a multivariate, linear repre- sentation of a vector of observables on its own lags. SVARs are used by economists to recover economic shocks from observables by imposing a minimum of assumptions compatible with a large class of models.

What is Vecm model?

Modern econometricians point out a method to establish the relational model among economic variables in a nonstructural way. They are vector autoregressive model (VAR) and vector error correction model (VEC). The VAR model is established based on the statistical properties of data.

How do var models work?

In the VAR model, each variable is modeled as a linear combination of past values of itself and the past values of other variables in the system. Since you have multiple time series that influence each other, it is modeled as a system of equations with one equation per variable (time series).

Due to heavy volume of vehicle registration, the numbers were given to the RTO offices of registration as well. The third part consists of one, two or three letters or no letters at all.
