Aggregating Data

 

Aggregating similar risks can reduce import and analysis times, as well as disk space requirements, while still maintaining the validity of loss estimates. If your exposure data contains multiple locations identified only by ZIP Code or subarea-level address information, you should consider aggregating your risks. You can aggregate data by combining risk counts, replacement values, and limit and deductible amounts for risks that do not have location detail records but do have the same information for the following fields:

         Address (ZIP Code or subarea information)

         Construction

         Year built

         Height

         Deductibles

To see results for occupancy, line of business, policy form, or other unique fields that can be lost during aggregation, add those fields to the aggregation fields listed in the previous paragraph.

  Make sure that similar risks are really similar before aggregating your data. For example, aggregating percent deductibles with dollar deductibles results in inappropriate loss estimates.
