)parameters from the feedback matrix in vector form
number of Monte Carlo replications
time series of the risk factors (T x F)
number of country-specific spanned factors (scalar)
inputs used in the estimation of the GVAR-based models (see "GVAR" function). Default is set to NULL
inputs used in the estimation of the JLL-based models (see "JLL" function). Default is set to NULL
string-list based which contains the labels of all variables present in the model
string-vector containing the names of the economies which are part of the economic system
string-vector containing the label of the model to be estimated
flag whether mean- (TRUE) or median- (FALSE) unbiased estimation is desired. Default is set to TRUE
