Sorry, I don't know much of anything about the module, I just noticed
that most of the documentation had not been merged into the new help
page.

The erratics in NODATA areas, I have no idea. Maybe a bug, maybe input
the program doesn't expect. Never properly updated for null support?

The memory problem could be solved with a debugger (like gdb) &/or a
memory profiler (like electric fence or valgrind). A C programmer or
someone familiar with UNIX might be required. Straight bug I think.

output for dominance analysis if undocumented might be best determined
by looking at the source code.

Hopefully someone out there uses these modules and can help...
