Abstract
The analysis of eight EXOSAT X-ray light curves of six active galactic nuclei by nonlinear prediction methods indicates that the observed variability is truly stochastic and is not caused by deterministic chaos. This result favours X-ray emission models with multiple centres of production of hot, possibly relativistic, electrons.Keywords
