(Internal) Apply fading to exposure record

Description

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:

Usage

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.

Value
