Monotonicity in Longitudinal Regressions

• In Event: Longitudinal and Multilevel Models

Abstract

Longitudinal regression models assess student growth over time. In tracking growth, it is reasonable to expect monotonic functions, even though they are not always attainable. This study investigates the use of growth models and provides recommendation for a technique that ensures monotonicity and provides reasonable fit.
