The input allocation in any given year should not be linked to realised, but to expected yields. Expected yields are constructed using the following modified Hodrick-Prescott filter: | The input allocation in any given year should not be linked to realised, but to expected yields.

+ | |||
+ | The regional database modules also cover some aspects which are discussed in other parts of this documentation. | ||
+ | * For policy data at the regional level (mostly premium related data) see Section 3.6. These policy related assignments require a good part of the CAPREG module | ||
+ | * For the fertiliser and feed allocations and environmental indicators, also important elements of the regional database, see the next Section 3.4 | ||
+ | * Towards the end of the regional data base consolidation supply side PMP parameters are calibrated as a final test of consistency and sometimes to serve as starting values for the subsequent baseline calibration (in gams\capreg\pmp.gms) | ||

+ | ===Build and compare time series of GHG inventories=== | ||
+ | The regionalised data base module CAPREG runs in two steps: | ||
+ | |||
+ | * The first steps prepares regional time series covering activities, production, land use and the fertiliser allocation | ||
+ | * The second step involves more time consuming processing steps which are therefore only executed for the selected base year: feed allocation, computation of GHG results, and the final calibration test | ||
+ | |||
+ | To assess the reliability of the CAPRI database in terms of GHG results against official UNFCCC notifications, | ||
