Re: the estimation procedure

Simone

In UrbanSim4, estimation has been added into the system. If you look at
the Eugene package you will find an estimation directory, and in it,
configuration and specification files, along with a run_estimation.py.
In the last file you will see that only one model is uncommented - you
can run this script to estimate the uncommented model, and this will run
the estimator for the selected model.

We will generate a tutorial and a section in the documentation to better
describe this capacity. For now, the best thing to do is experiment
with the estimation in the Eugene package and lean by imitating those
scripts for your Rome application.
