logistic transformation

a transformation in which measurements on a linear scale are converted into probabilities between 0 and 1. It is given by the formula y = e^x/(1 + e^x), where x is the scale value and e is the Eulerian number. The inverse of logits, logistic transformations are used in such statistical procedures as logistic regression.

noncontingent reinforcement

the process or circumstances in which a stimulus known to be effective as a reinforcer is presented independently of any particular behavior. Because contingencies may arise by accident (see accidental reinforcement), behavior-independent presentation of stimuli cannot guarantee that no contingency exists between a response and the stimuli. See reinforcement.
