Examples
- The variance problem can be reduced by smoothing the periodogram . various techniques to reduce spectral bias and variance are the subject of spectral estimation
周期图法是一个与物理学相关的小作品。你可以通过编辑或修订扩充其内容。 - Various apsd estimate arithmetics including periodogram method , correlogram method , blackman - tukey method , barlett method , yule - walker method , lda , and dga were implemented on ccs ( code composer studio )
谱估计算法分别采用了经典非参数方法中的周期图法、相关图法、 bt法、 bartlett法,和参数法中的yule - walker算法、 lda 、 dga 。 - 2 . the paper studies calendar effects of the sample , such as periodicity and long memory 。 so we use the flexible fourier form regression proves and filters the periodic components 。 and use ghp method to estimate the fractional integration d
用对数周期图法( gph )检验和估计序列长记忆行为。最后对去周期的收益序列建立了garch和egarch模型,较理想的拟合了价格的波动。 - We have do data analysis work . it is mainly work for our to show pressure signal , observe peak value of signal and compute signal power spectram . while we have conceive that used wavelet transform to distill pressure signal characteristic
频率域处理主要作了利用周期图法估计压力信号的功率谱，提出进一步的处理设想，利用小波分析的一些方法识别压力信号的特征。 - The ball mill load - control apparatus adopted the assembly language and the c51 language to program and its concerned software was designed , including the data collection , the wave - percolation , the short - time average over - zero ratio , the estimation of the power chart and the average - period chart
