The Cross-Autocorrelation Analysis Window is identical to the Semivariance Analysis Window except that cross-semivariance analysis (Z x Z2) rather than semivariance analysis (Z or Z2) is performed. Cross-semivariance analysis must be performed prior to cokriging. For a description of the commands and options provided in this window please see the Semivariance Analysis Window. Note that certain autocorrelation measures are not appropriate for cross-variate analysis and those tabs are not available in this window.
