What is VAR EViews 7?
VAR EViews 7 is a software package that offers access to statistical, forecasting, and modeling tools for econometric analysis. It is developed by Quantitative Micro Software and is widely used by academic researchers, corporations, government agencies, and students. One of the main features of VAR EViews 7 is its ability to handle vector autoregressive (VAR) models for multivariate time series.
What is a VAR model and how does it work?
A VAR model is a statistical model that captures the relationship between multiple variables as they change over time. For example, if you want to study how the GDP, inflation, and interest rate of a country affect each other over time, you can use a VAR model to do so. A VAR model consists of a system of equations that represents each variable as a linear function of its past values and the past values of the other variables in the system. For example, a simple VAR(1) model for three variables xt, yt, and zt can be written as:
xt = cx + φx,xxt-1 + φx,yyt-1 + φx,zzt-1 + ex,t
yt = cy + φy,xxt-1 + φy,yyt-1 + φy,zzt-1 + ey,t
zt = cz + φz,xxt-1 + φz,yyt-1 + φz,zzt-1 + ez,t
In this model, ci are constants, φi,j are coefficients, and ei,t are error terms. The subscript t denotes the time period, and the subscript i or j denotes the variable. The error terms are assumed to have zero mean and constant variance, and to be uncorrelated across time and variables. A higher-order VAR(p) model can include more lags of the variables in the system. A VAR model can be used to analyze the dynamic behavior of the variables, such as their impulse responses, forecast error variance decompositions, and Granger causality tests.
