Strange attractor in sliver evenness series

The chaotic phenomenon in terms of the observation time series of yar n evenness was studied. According to nonlinear dynamical systems(NDS ) theory, e vidence of chaotic behavior was searched:the correlation dimension and the large st Lyapunove exponent extracted was gotten from a single observed time series. The result shows that chaos exists in the series of yarn evenness which exhibit very differ ent character from white noise series.
