applyOverlapConstraintsToInfo function

(Internal) Modify item information using overlap constraints

applyOverlapConstraintsToInfo is an internal function for modifying item information using eligibility constraints. This is known as the big M method. The function penalizes item information of items that have been administered previously (within examinees). This leads to those items being deterred from selected in shadowtest assembly, unless necessary.

applyOverlapConstraintsToInfo(info, usage_flag, config, simulation_constants)

Arguments

• info: a length-ni vector containing item information on each item, intended for shadow-test assembly.
• usage_flag: a length-ni vector containing how many times each item has been administered previously to the examinee.
• config: a config object.
• simulation_constants: a named list containing simulation constants.

Returns

applyEligibilityConstraintsToInfo returns an updated item information vector.
