原文:
where α is the assumed lag-1 autocorrelation, x0 = 0, and zn is taken from Gaussian white noise.
Thus, by choosing an appropriate lag-1 autocorrelation, one can use (16) to model a red-noise spectrum.
This red-noise was estimated from (α1+ √α2)/2, where α1 and α2 are the lag-1 and lag-2 autocorrelations of the Nino3 SST.
也就是说,所有用lag-1=0.72的小波分析都是错的,因为0.72只是对于nino3 sst的红噪声自相关系数,是要自己算的。 |
