Usage

eyeprocess_irt_bank_coverage(
  items,
  theta = seq(-4, 4, length.out = 161),
  target_information = 5,
  target = c(-2, 2)
)

Arguments

items: Item-parameter data frame or item collection.
theta: Latent-trait value or vector of latent-trait values.
target_information: Target test-information level.
target: Target level, distribution, or criterion.
