applyFading function

(Internal) Apply fading to exposure record

applyFading is an internal function for applying fading to exposure record. Specifically, the following exposure records are multiplied by fading_factor:

• n_k: the number of examinees completed the test so far, at each segment k.
• f_k:
• a_ik: the number of times each item i was administered to examinees, at each segment k
• r_ik:

applyFading(exposure_record, segments_to_apply, simulation_constants)

Arguments

• exposure_record: a named list containing exposure records.
• segments_to_apply: which segments to apply fading to.
• simulation_constants: a named list containing simulation constants.

Returns

applyFading returns an updated exposure record.
