3. Employing the random walk model , the white - noise models and nonlinear models to test the weak efficient market of china " s capital market , this essay find that china " s capital market hasn " t reached the lowest efficient market
   本研究采用随机游走模型( therandomwalkmodel ) 、白噪声过程模型( thewhite - noisemodels )和非线性模型( nonlinearmodels )对我国资本市场进行弱型有效市场检验，结果表明，迄今为止我国资本市场还没有达到最低层次的有效市场状态。
4. In chapter 4 , i performed the analyzing work with wavelet and fastica and find that wavelet was a high efficient way to filter the cep signal when i set the wavelet and scaling function to haar , decomposing level to 4 , threshold method to fixed to threshold and white - noise structure to scaled white - noise . it took the advantage that reduced the accumulating times to 60 with more smooth signal and less distortion . but fastica takes no advantage on this facet
   本文通过小波变换和独立分量快速分析模式识别的方法对cep数据进行了分析处理，同时与数字低通椭圆滤波器的处理效果进行了比较，发现用小波对cep的数据进行滤波处理时，可以将数据的叠加次数从120降低到60次左右，且信号的质量要比以前的处理方法好；但是独立分量快速分析方法效果不很好。
