MSBVAR (version 0.9-2)

reduced.form.var: Estimation of a reduced form VAR model

Description

Estimates a reduced form VAR using equation-by-equation seemingly unrelated regression (SUR).

Usage

reduced.form.var(Y, p, z=NULL)

Arguments

Y

$T x m$ multiple time series object created with ts().

p

Lag length

z

$T x k$ exogenous variables in a matrix of $T$ rows. Can be NULL if there are none.

Value

List of class "VAR" with elements,

intercept

Row vector of the $m$ intercepts.

ar.coefs

$m x m x p$ array of the AR coefficients. The first $m x m$ array is for lag 1, the p'th array for lag p.

Bhat

$(mp + k + 1) x m$ matrix of the coefficients, where the columns correspond to the variables in the VAR. Intercepts follow the AR coefficients, etc.

exog.coefs

$k x m$ matrix of exogenous coefficients, or NA if z=NULL

vcv

$m x m$ matrix of the maximum likelihood estimate of the residual covariance

mean.S

$m x m$matrix of the posterior residual covariance.

hstar

$mp x mp$ right hand side variables crossproduct.

X

Right hand side variables for the estimation of BVAR

Y

Left hand side variables for the estimation of BVAR

y

Input data (Y)

Details

This is a frequentist VAR estimator. This is a workhorse function --- you will want to use other functions such as irf, mc.irf or dfev to report and interpret the results of this object.
