用来产生均匀分布或高斯分布的伪随机数 （近似白噪声），它们可具有不同的均值和方差。用REMEZ算法求交错点组。用Cholesky分解求ARMA模型的参数并作谱估计。求MA模型的参数 并估计功率谱。　　用最小方差法估计序列 的功率谱。-used to produce uniform or Gaussian distribution of the pseudo-random number (similar to white noise). They may have a different mean and variance. Application of Remez algorithm used for staggered Point Group. Cholesky decomposition used for ARMA model and the parameters estimated for the spectrum. MA for the model parameters and the estimated power spectrum. With MVM sequence of the estimated power spectrum.
