The Society for the Quantitative Analyses of Behavior (SQAB) was founded in 1978 by Michael Lamport Commons and John Anthony Nevin to present symposia and publish material which bring a quantitative analysis to bear on the understanding of behavior. This International Society holds its annual meeting in conjunction with the Association for Behavior Analysis ( ABA). Talks at SQAB focus on the development and use of mathematical formulations to: characterize one or more dimensions of an obtained data set, derive predictions to be compared with data, and generate novel data analyses.
