Additive and Multiplicative Models for Gamma Distributed Random Variables, and Their Application as Psychometric Models for Response Times.

Maris, Eric

Psychometrika, v58 n3 p445-69 Sep 1993

A class of models is presented for gamma distributed random variables. These additive, multiplicative, and combined additive-multiplicative models are more flexible than classical linear models with respect to the structure that can be imposed on expected values. As a special case, a class of psychometric models for reaction times is presented. (SLD)
