If you only want the user docs you can find them here...

        http://rsb.info.nih.gov/ij/docs/menus/analyze.html#set



But you said "documentation about the code", so your best bet is to  
examine the code itself. Check out the source online at

        http://rsb.info.nih.gov/ij/developer/source/index.html

and look for image class that extends ImageStatistics.  For example,  
if you want to see how it is done for a byte image, check out  
ByteStatistics.  Once there, you'll see the calculateMoments method.

Cheers,
Ben
