Re: Industrial ELCM error

Quinn,

Your error message suggests that you don't have enough space to
accommodate industrial jobs. Specifically, the variable
vacant_industrial_job_space (I suppose) produces only zeros and thus there
are no gridcells to sample from in order to have a set of alternatives for
the choice model.

Let me know if you find out that this is a wrong hypothesis.
