.. py:function:: add_cpc_classification_from_single_reference_product(db)


.. py:function:: assign_single_product_as_activity(db)


.. py:function:: create_composite_code(db)

   Create composite code from activity and flow names


.. py:function:: delete_exchanges_missing_activity(db)

   Delete exchanges that weren't linked correctly by ecoinvent.

   These exchanges are missing the "activityLinkId" attribute, and the flow they want to consume is not produced as the reference product of any activity. See the `known data issues <http://www.ecoinvent.org/database/ecoinvent-version-3/reports-of-changes/known-data-issues/>`__ report.



.. py:function:: delete_ghost_exchanges(db)

   Delete technosphere which can't be linked due to ecoinvent errors.

   A ghost exchange is one which links to a combination of *activity* and *flow* which aren't provided in the database.


.. py:function:: delete_none_synonyms(db)


.. py:function:: drop_temporary_outdated_biosphere_flows(db)

   Drop biosphere exchanges which aren't used and are outdated


.. py:function:: es2_assign_only_product_with_amount_as_reference_product(db)

   If a multioutput process has one product with a non-zero amount, assign that product as reference product.

   This is by default called after ``remove_zero_amount_coproducts``, which will delete the zero-amount coproducts in any case. However, we still keep the zero-amount logic in case people want to keep all coproducts.


.. py:function:: fix_ecoinvent_flows_pre35(db)


.. py:function:: fix_unreasonably_high_lognormal_uncertainties(db, cutoff=2.5, replacement=0.25)

   Fix unreasonably high uncertainty values.

   With the default cutoff value of 2.5 and a median of 1, the 95% confidence
   interval has a high to low ratio of 20.000.


.. py:function:: link_biosphere_by_flow_uuid(db, biosphere='biosphere3')


.. py:function:: link_internal_technosphere_by_composite_code(db)

   Link internal technosphere inputs by ``code``.

   Only links to process datasets actually in the database document.


.. py:function:: remove_uncertainty_from_negative_loss_exchanges(db)

   Remove uncertainty from negative lognormal exchanges.

   There are 15699 of these in ecoinvent 3.3 cutoff.

   The basic uncertainty and pedigree matrix are applied rather blindly,
   and the can produce strange net production values. It makes much more
   sense to assume that these loss factors are static.

   Only applies to exchanges which decrease net production.



.. py:function:: remove_unnamed_parameters(db)

   Remove parameters which have no name. They can't be used in formulas or referenced.


.. py:function:: remove_zero_amount_coproducts(db)

   Remove coproducts with zero production amounts from ``exchanges``


.. py:function:: remove_zero_amount_inputs_with_no_activity(db)

   Remove technosphere exchanges with amount of zero and no uncertainty.

   Input exchanges with zero amounts are the result of the ecoinvent linking algorithm, and can be safely discarded.


.. py:function:: set_lognormal_loc_value(db)

   Make sure ``loc`` value is correct for lognormal uncertainty distributions
