1st year GIS student here...I have been given the task to perform Global and Local Moran's I index to incorporate into a cluster map and a significance map. I had to add fields of Percent Hispanic and Density Hispanic based on county population, in which I calculated.I am working with both blocks and roads shapefiles. When I run the Autocorrelation tool, I get a high Z-score (239-577) and at least two messages about threshold values and neighbors ..... ; I have tried other Conceptualization relationships yet the tool would not work at all. I just want to make sure I am setting my parameters correctly. Also, was still not sure if I needed to perform any type of joins.... Please help.
