You might want to take a look at this question (How to implement Spatial Autocorrelation using QGIS or PostgreSQL (or any free application)?) and look at programmatic solutions like R. QGIS may be another option as well.
This website outlines different formulas and measures for spatial autocorrelation that may also be of interest to you

You can also use:
- the Python module PySAL: Spatial Autocorrelation. You can use it in the Python console of QGIS or in a script in the Processing Toolbox
- R (Applied Spatial Data Analysis with R: analysis with R, “The Problem of Spatial Autocorrelation:” forty years on, Geary's C test for spatial autocorrelation, for example, but there are many others)
- gvSIG and OpenJUMP with the Sextante Toolbox
