Abstract:	Quasar variability has long held the promise of shedding light on the detailed structure of active galactic nuclei, and possibly other astrophysical phenomena. Different emission mechanisms lead to different patterns of variability in quasar flux which are in principle easily distinguishable. Recent predictions for the expected spectrum of variations for various models are now in such a form that they can be compared with the statistical properties of quasar light curves from large scale monitoring programmers. In this paper, we use the results of a long term monitoring programme of a large sample of quasars, as well as light curves for individual active galactic nuclei from the literature, to distinguish between the various model predictions.
