Anauto-regressive model is an approach to statistical analysis used inlongitudinal research. These models involve regressing an outcome variable ofinterest onto measures of that variable at previous time points. The resultingresidual variance provides an estimate of change in the variable.Auto-regressive models can be used to examine the longitudinal relationshipsbetween variables as well as the rank-order stability of individual differencesin performance on a particular variable over time.
