applyEligibilityConstraintsToInfo function

(Internal) Modify item information using eligibility constraints

applyEligibilityConstraintsToInfo 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 are marked as ineligibile. This leads to those items being deterred from selected in shadowtest assembly, unless necessary.

applyEligibilityConstraintsToInfo(
  info,
  eligibility_flag_in_current_theta_segment,
  config,
  simulation_constants
)

Arguments

• info: a length-ni vector containing item information on each item, intended for shadow-test assembly.
• eligibility_flag_in_current_theta_segment: a list containing eligibility flags for the current theta segment.
• config: a config_Shadow object. Use createShadowTestConfig for this.
• simulation_constants: a named list containing simulation constants.

Returns

applyEligibilityConstraintsToInfo returns an updated item information vector.
