If I have two arrays that are identical except for a shift: import numpy as np from scipy import signal x = [4,4,4,4,6,8,10,8,6,4,4,4,4,4,4,4,4,4,4,4,4,4,4] y =
I try to implement the spatial spectrum from the above equation (attached) Where kX, kY are the grid points in k space, C(w,r) - cross spectral densities betwe
I have three time-series variables (x,y,z) measured in 3 replicates. x and z are the independent variables. y is the dependent variable. t is the time variable
I have been struggling the last days trying to compute the degrees of freedom of two pair of vectors (x and y) following reference of Chelton (1983) which is:
