Research on the chaotic time series decision method

Before extracting the chaotic characteristic of the time series,it is needed to consider whether this time series have the chaos.If it is assumed that the experimental data is chaotic without examination in advance and the reconstruction phase space theory is used directly to extract the time series characteristics to build the model and the forecast,the result will be incredible.The chaotic system usually can be identified by the existence of chaotic attractors.Around this characteristics,this paper discussed the chaotic time series decision method.
