384 11. Vector Autoregressive Models for Multivariate Time Series This chapter is organized as follows. Section 11.2 describes speciﬁcation, estimation and inference in VAR models and introduces the S+FinMetrics

V = var( A ) returns the variance of the elements of A along the first array dimension whose size does not equal 1. If A is a vector of observations, the variance is a

If A is a matrix whose columns are random variables and whose rows are observations, V is a row vector containing the variances corresponding to each column. A varm model object is a MATLAB ® variable containing properties that describe the model, such as AR polynomial degree p, response dimensionality n, and coefficient values. varm must be able to infer n and p from your specifications; n and p are not estimable. Description var supports financial time series objects based on the MATLAB ® var function. The varm function returns a varm object specifying the functional form and storing the parameter values of a p -order, stationary, multivariate vector autoregression model (VAR (p)) model. To create a model of multiple time series data, decide on a VAR model form, and fit parameters to the data.

If A is a vector of observations, the variance is a scalar. If A is a matrix whose columns are random variables and whose rows are observations, V is a row vector containing the variances corresponding to each column. A varm model object is a MATLAB ® variable containing properties that describe the model, such as AR polynomial degree p, response dimensionality n, and coefficient values.

VAR Model Estimation Preparing VAR Models for Fitting. To create a model of multiple time series data, decide on a VAR model form, and fit parameters to the data. Run the command by entering it in the MATLAB Command Window. Web browsers do not support MATLAB commands.

V = var(A,w,'all') computes the variation over all elements of A when w is either 0 or 1.This syntax is valid for MATLAB ® versions R2018b and later. MATLAB Code for TVP-VARs. Code for TVP-VAR using the Carter and Kohn (1994) algorithm as implemented in Primiceri (2005) is available here.

From the matlab documentation, VAR normalizes Y by N-1, where N is the sample size. This is an unbiased estimator of the variance of the population from which X is drawn, as long as X consists of independent, identically distributed samples. but. Y = VAR(X,1) normalizes by N and produces the second moment of the sample about its mean.
