Calculates the Cross-covariance between multiple wavelet transfomations (dwt or modwt)
wccv(x, decomp = "modwt", filter = "haar", nlevels = NULL)Returns a matrix of lists of all the possible pair cross-covariance, variance of each wavelet cross-covariance and its 95
A vector with dimensions N x M.
A string that indicates whether to use the "dwt" or "modwt" decomposition.
A string that specifies what wavelet filter to use.
An integer that indicates the level of decomposition. It must be less than or equal to floor(log2(length(x))).

If nlevels is not specified, it is set to \(\left\lfloor {{{\log }_2}\left( {length\left( x \right)} \right)} \right\rfloor\)
