Get bounds for the parameters in the covariance matrix

Get bounds for the parameters in the covariance matrix

Usage

get_bounds_covariance(d, lower, upper, covariance = "symmetric")

Arguments

d

Integer denoting the dimensionality of the model.

lower, upper

Numeric value containing the value of the lower and upper bounds for the covariance matrix.

covariance

Character denoting the structure of the covariance matrix. Can either be "symmetric" (symmetric around the diagonal) or "isotropic" (diagonal). Defaults to "symmetric".

Value

List containing two numeric vectors of lower and upper bounds for the covariance matrix in that order.

Examples

get_bounds_covariance(
  2, 
  0,
  1,
  covariance = "symmetric"
)
#> [[1]]
#> [1] 0 0 0
#> 
#> [[2]]
#> [1] 1 1 1
#> 

get_bounds_covariance(
  2,
  0, 
  1,
  covariance = "isotropic"
)
#> [[1]]
#> [1] 0 0
#> 
#> [[2]]
#> [1] 1 1
