How to solve the geospatial autocorrelation problem using Moran in the proc variogram process step?

_Sas_Beginner_ — Sun, 26 Mar 2023 09:51:51 GMT

SIMILAR TO GEODA SOFTWARE, FIRST MAKE GEOSPATIAL WEIGHTS FOR THE MAP, AND THEN ADD DATA TO DIRECTLY CALCULATE MORAN'S I AND LOCAL MORAN, I WANT TO DO THE SAME IN PROC VARIOGRAM, BUT I CAN'T FIND THE RELEVANT OPTIONS AND SETTINGS, WHAT SHOULD I DO? PLEASE!!!
