Reform structural parameter vector into the "standard" form
Description
reform_structural_pars
reforms (unconstrained) structural
parameter vector into the form that corresponds to reduced form parameter vectors.
Usage
reform_structural_pars(
p,
M,
d,
params,
model = c("GMVAR", "StMVAR", "G-StMVAR"),
structural_pars = NULL
)
Arguments
p |
a positive integer specifying the autoregressive order of the model. |
M |
|
d |
the number of time series in the system. |
params |
a real valued vector specifying the parameter values.
Above, In the GMVAR model, The notation is similar to the cited literature. |

Details
If the structural parameter vector is a constrained one, use
reform_constrained_pars
first to remove the constraints.
Value
Returns (unconstrained) "reduced form model" parameter vector.
Warning
No argument checks!
