varnames: A character vector of variable names.
expectation: A numeric vector of expectations.
covariance: A numeric matrix (or a numeric scalar) for covariances.

Examples

bl1 <- bl(
  name = "Example 1",
  varnames = c("x", "y", "z"),
  expectation = c(1, 2, 3),
  covariance = matrix(c(
    1, 0.5, 0.5,
    0.5, 1, 0.5,
    0.5, 0.5, 1
  ), 3, 3)
)
