Sigma_g

an NxNxG array of starting values for the group parameter \(\mathbf{\Sigma}_g\).

V

an KxK matrix of starting values for the global parameter \(\mathbf{V}\).

nu

a positive scalar with starting values for the global parameter \(\nu\).

m

a positive scalar with starting values for the global hyper-parameter \(m\).

w

Method new()

Create new starting values StartingValuesBVARGROUPPRIORPANEL

Usage

specify_starting_values_bvarGroupPriorPANEL$new(
  group_allocation = 1:C,
  C,
  G = C,
  N,
  p,
  d = 0
)

Arguments

group_allocation

a numeric vector with integer numbers denoting group allocations

C

a positive integer - the number of countries in the data.

G

a positive integer specifying the number of country groups.

N

a positive integer - the number of dependent variables in the model.

p

a positive integer - the autoregressive lag order of the SVAR model.

d

a positive integer - the number of exogenous variables in the model.

Returns

Starting values StartingValuesBVARGROUPPRIORPANEL

Examples

# starting values for Bayesian Panel VAR 2-country model with 4 lags for a 3-variable system.
sv = specify_starting_values_bvarGroupPriorPANEL$new(C = 2, N = 3, p = 1)

---

Method get_starting_values()

Returns the elements of the starting values StartingValuesBVARGROUPPRIORPANEL as a list.

Usage

specify_starting_values_bvarGroupPriorPANEL$get_starting_values()

Examples

# starting values for a homoskedastic bsvar with 1 lag for a 3-variable system
sv = specify_starting_values_bvarGroupPriorPANEL$new(rep(1,2), C = 2, N = 3, p = 1)
sv$get_starting_values()   # show starting values as list

---

Method set_starting_values()

Returns the elements of the starting values StartingValuesBVARGROUPPRIORPANEL as a list.

Usage

specify_starting_values_bvarGroupPriorPANEL$set_starting_values(last_draw)

Arguments

last_draw

a list containing the same elements as object StartingValuesBVARGROUPPRIORPANEL

Returns

An object of class StartingValuesBVARGROUPPRIORPANEL including the last draw of the current MCMC as the starting value to be passed to the continuation of the MCMC estimation.

Examples

sv = specify_starting_values_bvarGroupPriorPANEL$new(rep(1,2), C = 2, N = 3, p = 1)
# Modify the starting values by:
sv_list = sv$get_starting_values()   # getting them as list
sv_list$A <- matrix(rnorm(12), 3, 4) # modifying the entry
sv$set_starting_values(sv_list)      # providing to the class object

---

Method clone()

The objects of this class are cloneable with this method.

Usage

specify_starting_values_bvarGroupPriorPANEL$clone(deep = FALSE)

Arguments

deep

Whether to make a deep clone.

Examples

# starting values for a Bayesian Panel VAR
sv = specify_starting_values_bvarGroupPriorPANEL$new(rep(1,2), C = 2, G = 1, N = 3, p = 1)
