Description

Item-based example item pool (1000 items).

Details

This pool is associated with the following objects:

• itempool_science an item_pool object containing 1000 items.

• itemattrib_science an item_attrib object containing 9 item-level attributes.

• constraints_science a constraints object containing 36 constraints.

Also, the following objects are intended for illustrating expected data structures.

• itempool_science_data a data.frame containing item parameters.

• itemattrib_science_data a data.frame containing item attributes.

• constraints_science_data a data.frame containing constraint specifications.

Examples

itempool_science    <- loadItemPool(itempool_science_data)
itemattrib_science  <- loadItemAttrib(itemattrib_science_data, itempool_science)
constraints_science <- loadConstraints(constraints_science_data,
  itempool_science, itemattrib_science)
