backward elimination

a technique used in regression analysis in which the goal is to forecast an outcome or response variable according to a subset of predictor variables narrowed down from a large initial set. In background elimination, all available predictors are included originally and then examined one at a time, with any predictors that do not contribute in a statistically meaningful manner systematically dropped until a predetermined criterion is reached. Also called backward deletion; backward selection; stepdown selection. See also stepwise regression.

cochlear implant

an electronic device designed to enable individuals with complete deafness to hear and interpret some sounds, particularly those associated with speech. It consists of a microphone to detect sound, a headpiece to transmit sound, a processor to digitize sound, and a receiver to signal electrodes that are surgically implanted in the cochlea to stimulate the auditory nerve. In contrast to a hearing aid, which amplifies sound, it directly stimulates the auditory nerve.
