regress on

to determine the extent to which a given dependent variable (y) can be explained or predicted by a number of independent variables (xs). For example, a researcher may be interested in learning how scores on a measure of relationship commitment vary as a function of age, relationship status, time in relationship, and shared experiences. That is, the researcher may regress y on x. See regression analysis.

cocaine withdrawal

cocaine withdrawal

in DSM–IV–TR, a characteristic withdrawal syndrome that develops after cessation of (or reduction in) prolonged, heavy consumption of cocaine. The essential characteristic is depressed mood, sometimes severe, and there may also be fatigue, disturbed sleep, increased appetite, vivid and unpleasant dreams, or psychomotor retardation or agitation, or all of these features. Marked withdrawal symptoms (see crash) often follow an episode of intense, high-dose use. The equivalent term in DSM–5 is stimulant withdrawal. See also substance withdrawal.
