Re: [UrbanSim-Users] estimating development_project_location_choice_model

Hi Hana,

We checked this out and in the process built a simplified
development_constraints table (see below) that we hoped would work for
now, but sadly it did not.

What else should we look at?

Also, we don't understand well why before the estimation of dplcm-
residential, for which we've only specified one variable
(urbansim.gridcell.ln_residential_units) for our current testing, the
land price model is being run. I suppose it's run before the
estimation because land prices are a criterion for dplcm, but I'm
wondering where this relationship is defined if not in the dplcm model
specification.

Thanks,

Brian
