Same function as A_CORRELATE but accept array (until 4 dimension) for input and do the autocorrelation or the autocovariance along the time dimension which must be the last one of the input array.
This function computes the "time cross correlation" Pxy(L) or the "time cross covariance" between 2 arrays (this is some kind of C_CORRELATE but for multidimensional arrays) as a function of the lag (L).
Same function as SKEWNESS but accept array (until 4 dimension) for input and perform the skewness along the time dimension which must be the last one of the input array.
