The class StartingValuesBSVARSV presents starting values for the bsvar model with Stochastic Volatility heteroskedasticity.
bsvars::StartingValuesBSVAR
-> StartingValuesBSVARSV
A
an NxK
matrix of starting values for the parameter A
.

an NxN
matrix of starting values for the parameter B
.
hyper
a (2*N+1)x2
matrix of starting values for the shrinkage hyper-parameters of the
hierarchical prior distribution.
h
an NxT
matrix with the starting values of the log-volatility processes.
rho
an N
-vector with values of SV autoregressive parameters.
omega
an N
-vector with values of SV process conditional standard deviations.
sigma2v
an N
-vector with values of SV process conditional variances.
S
an NxT
integer matrix with the auxiliary mixture component indicators.
sigma2_omega
an N
-vector with variances of the zero-mean normal prior for \omega_n
.
s_
a positive scalar with the scale of the gamma prior of the hierarchical prior for \sigma^2_{\omega}
.
new()
Create new starting values StartingValuesBSVARSV.
specify_starting_values_bsvar_sv$new(N, p, T, d = 0)
N
a positive integer - the number of dependent variables in the model.
p
a positive integer - the autoregressive lag order of the SVAR model.
T
a positive integer - the the time series dimension of the dependent variable matrix Y
.
d
a positive integer - the number of exogenous
variables in the model.
Starting values StartingValuesBSVARSV.
get_starting_values()
Returns the elements of the starting values StartingValuesBSVARSV as a list
.

# starting values for a bsvar model with 1 lag for a 3-variable system sv = specify_starting_values_bsvar_sv$new(N = 3, p = 1, T = 100) sv$get_starting_values() # show starting values as list
set_starting_values()
Returns the elements of the starting values StartingValuesBSVAR_SV as a list
.
specify_starting_values_bsvar_sv$set_starting_values(last_draw)
last_draw
a list containing the last draw of the current MCMC run.
An object of class StartingValuesBSVAR including the last draw of the current MCMC as the starting value to be passed to the continuation of the MCMC estimation using estimate()
.
