Method new()

Create a new specification of the BSVAR model with t-distributed structural shocks, BSVART.

Usage

specify_bsvar_t$new(
  data,
  p = 1L,
  B,
  A,
  exogenous = NULL,
  stationary = rep(FALSE, ncol(data))
)

Arguments

data

a (T+p)xN matrix with time series data.

p

a positive integer providing model's autoregressive lag order.

B

a logical NxN matrix containing value TRUE for the elements of the structural matrix \(B\) to be estimated and value FALSE for exclusion restrictions to be set to zero.

A

a logical NxK matrix containing value TRUE for the elements of the autoregressive matrix \(A\) to be estimated and value FALSE for exclusion restrictions to be set to zero.

exogenous

a (T+p)xd matrix of exogenous variables.

stationary

an N logical vector - its element set to FALSE sets the prior mean for the autoregressive parameters of the Nth equation to the white noise process, otherwise to random walk.

Returns

A new complete specification for the bsvar model with t-distributed structural shocks, BSVART.

Method clone()

The objects of this class are cloneable with this method.

Usage

specify_bsvar_t$clone(deep = FALSE)

Arguments

deep

Whether to make a deep clone.

Examples

data(us_fiscal_lsuw)
spec = specify_bsvar_t$new(
   data = us_fiscal_lsuw,
   p = 4
)
#> The identification is set to the default option of lower-triangular structural matrix.
