Siva,

Unfortunately, we don't have documentation for estimation yet. But you
can follow the following steps:

1. Create a cache directory from your database (see
http://www.urbansim.org/docs/opus-userguide/node22.html )
    - Use the eugene/configs/baseline.py file as configuration, just

      modify the entries 'input_configuration' and 'cache_directory'.

2. In the file eugene/estimation/run_estimation.py uncomment the model
you want to estimate.

3. In eugene/estimation/my_estimation_config.py set the entry
'cache_directory' to the location where your cache data is. Also, set
the 'output_configuration' to a database where you want to have the
results. ('input_configuration' is not used here.)

4. Modify the file eugene/estimation/{model}_specification.py for the
{model} you are estimating by adding or removing variables.

5. Run eugene/estimation/run_estimation.py.
(Results will be stored into the database as well as the cache
directory, if the argument save_estimation_results is set to True.)

I hope it helps.
