’ or of class
‘vec2var
’ with confidence bands.

object |
An object of class ‘ |
n.ahead |
An integer specifying the number of forecast steps. |
ci |
The forecast confidence interval |
dumvar |
Matrix for objects of class ‘ |
... |
Currently not used. |
The n.ahead
forecasts are computed recursively for the
estimated VAR, beginning with h = 1, 2, …, n.ahead:
\bold{y}_{T+1 | T} = A_1 \bold{y}_T + … + A_p \bold{y}_{T+1-p} + C D_{T+1}
The variance-covariance matrix of the forecast errors is a function of Σ_u and Φ_s.
A list with class attribute ‘varprd
’ holding the
following elements:
fcst |
A list of matrices per endogenous variable containing the forecasted values with lower and upper bounds as well as the confidence interval. |
endog |
Matrix of the in-sample endogenous variables. |
model |
The estimated VAR |
exo.fcst |
If applicable provided values of exogenous variables,
otherwise |
