Abstract

Direct estimation of the largest Lyapunov exponent from deterministically chaotic data is well established. From stochastic data a finite, positive value is obtained as well; we show how it is determined by spectral properties of the signal and by computational parameters. Distinction of chaos versus noise is discussed.
