  • Abstract

    After analyzing the advantages and disadvantages of dynamical system and statistical system.some simple models with the equations of Lorenz system and auto-regresslon model have been respectively set up,and comparative experiments conducted.The result of the research demonstrates that in chaotic parametric domain,the accuracy of statistical forecast is higher than that of dynamical forecast,while in non-chaotic parametric domain,dynamical forecast is more accurate than statistical forecast.
