Mean of VAR process

Syntax

M = mean(V)

Input arguments

Output arguments

Description

For plain VAR objects, the output argument X is a column vector where the k-th number is the asymptotic mean of the k-th variable, or NaN if the k-th variable is non-stationary (contains a unit root).

In panel VAR objects (with a total of Ng groups) and/or VAR objects with multiple alternative parameterisations (with a total of Na parameterisations), X is an Ny-by-Ng-by-Na matrix in which the column X(:,g,a) is the asyptotic mean of the VAR variables in the g-th group and the a-th parameterisation.

In VAR objects with exogenous inputs, the mean will be computed based on the asymptotic assumptions of exogenous inputs assigned by the function xasymptote.
