[UrbanSim-Users] interpreting an error message

Hello,

I'm troubleshooting our models to identify problems such as data
missing from/improperly formatted in our base year.

In at least two cases (industrial employment relocation model, and
household location choice model), I'm seeing the same proximate error:

   File "C:\opusworkspace-svn\opus_core\misc.py", line 515, in ncumsum
     str(prob_array.sum(axis=axis, dtype=dtype))
ValueError: The probability array must sum up to 1. It is -1.#IND

What I'm looking for is a suggested strategy for interpreting this
error in these disparate cases.

Thanks,

Brian
