我在学习外文的方法，中间有句话一直没看懂，现摘录出来，求哪位高手指点我一二。我做EMD分解成IMFs，再判断其高斯性 For the Gaussianity criterion, the magnitude of each IMF Bispectrum is compared with the Bootstrap estimated Bispectrum value, of a simulated Gaussian noise signal having the same number of samples with the noisy signal. its Bispectrum magnitude should lie inside the range of the Bootstrap estimated Bispectrum values of a simulated Gaussian noise signal having equal length with the original signal。 我计算出来的Bispectrum magnitude是个128×128矩阵，通过Bootstrap自助法估计的双谱值也是1000组这样的，取其最大和最小两组，请问我如何去判定是否在自助法得到的范围之内？ 我只有18金币，全部拿出来了，送给高手 |
