Visual observations of the variable star Z And for the period 1993-1996 were analyzed from the perspective of dynamical systems theory. Background noise and signal detection were estimated by the use of an Autoregressive model and Singular Spectrum Analysis. The results suggest this time series possesses an attractor with a correlation dimension d_s=9.33±0.06.
